An "on" signal (typically over 2.3 Volts) presented at pin 5 of U2 in Fig. 5D causes a transmission at a frequency above the median frequency. These signals are received by the corresponding receiver Ul . Output signal from pin 6 of Ul is fed to the comparator 280 of Figs. 4 and 6 that is operative to determine whether the received signal is "off" or "on", respectively. It is also possible to use the comparator that is contained within Ul by connecting pin 7 of Ul of Fig. 5D, through pin 6 of the connector Jl of Fig. 5D, pin 6 of connector Jl of Fig. 5A, through the jumper to pin 12 ofUl of Fig. 5A. Preferably, receipt of an on signal or spike of duration less than 0.01 * T is ignored. Receipt of an on signal as shown in Fig. 10B, of duration between 0.01 * T and 0.40 * T is preferably taken to be a bit with value 0. Receipt of an on signal as shown in Fig. 10C, of duration greater than 0.40 * T is preferably taken to be a bit with value 1. Typically, T has a value of 1.0 millisecond. Furthermore, after receipt of an on signal, the duration of the subsequent off signal is measured. The sum of the durations of the on signal and the off signal must be between 0.90 T and 1.10 T for the bit to be considered valid. Otherwise, the bit is considered invalid and is ignored. Reference is now made to Fig. 11, which is a simplified flowchart illustration of a method for generating control instructions for the apparatus of Fig. 1A. The method of Fig. 11 preferably includes the following steps: A toy is selected (step 550). At least one command is selected, preferably from a plurality of commands associated with the selected toy (steps 560 - 580). Alternatively, a command may be entered by selecting, modifying, and creating a new binary command (step 585). Typically, selecting a command in steps 560 - 580 may include choosing a command and specifying one or more control parameters associated with the command. A control parameter may include, for example, a condition depending on a result of a previous command, the previous command being associated either with the selected toy or with another toy. A control parameter may also include an execution condition governing execution of a command such as, for example: a condition stating that a specified output is to occur based on a status of the toy, that is, if and only if a specified input is received; a condition stating that the command is to be performed at a specified time; a condition stating that performance of the command is to cease at a specified time; a condition comprising a command modifier modifying execution of the command, such as, for example, to terminate execution of the command in a case where execution of the command continues over a period of time; a condition dependent on the occurrence of a future event; or another condition. The command may comprise a command to cancel a previous command. The output of the method of Fig. 11 typically comprises one or more control instructions implementing the specified command, generated in step 590. Typically, the one or more control instructions are comprised in a command file. Typically, the command file is called from a driver program which typically determines which command is to be executed at a given point in time and then calls the command file associated with the given command. Preferably, a user of the method of Fig. 11 performs steps 550 and 560 using a computer having a graphical user interface. Reference is now made to Figs. 12A - 12C, which are pictorial illustrations of a preferred embodiment of a graphical user interface implementation of the method of Fig. 11. Fig. 12 A comprises a toy selection area 600, comprising a plurality of toy selection icons 610, each depicting a toy. The user of the graphical user interface of Figs. 12A - 12C typically selects one of the toy selection icons 610, indicating that a command is to be specified for the selected toy. Fig. 12 A also typically comprises action buttons 620, typically comprising one or more of the following: a button allowing the user, typically an expert user, to enter a direct binary command implementing an advanced or particularly complex command not otherwise available through the graphical user interface of Figs. 12A - 12C; a button allowing the user to install a new toy, thus adding a new toy selection icon 610; and a button allowing the user to exit the graphical user interface of Figs. 12A - 12C. Fig. 12B depicts a command generator screen typically displayed after the user has selected one of the toy selection icons 610 of Fig. 12 A. Fig. 12B comprises an animation area 630, preferably comprising a depiction of the selected toy selection icon 610, and a text area 635 comprising text describing the selected toy. Fig. 12B also comprises a plurality of command category buttons 640, each of which allow the user to select a category of commands such as, for example: output commands; input commands; audio in commands; audio out commands; and general commands. Fig. 12B also comprises a cancel button 645 to cancel command selection and return to the screen of Fig. 12 A. Fig. 12C comprises a command selection area 650, allowing the user to specify a specific command. A wide variety of commands may be specified, and the commands shown in Fig. 12C are shown by way of example only. Fig. 12C also comprises a file name area 655, in which the user may specify the name of the file which is to receive the generated control instructions. Fig. 12C also comprises a cancel button 645, similar to the cancel button 645 of Fig. 12B. Fig. 12C also comprises a make button 660. When the user actuates the make button 660, the control instruction generator of Fig. 11 generates control instructions implementing the chosen command for the chosen toy, and writes the control instructions to the specified file. Fig. 12C also comprises a parameter selection area 665, in which the user may specify a parameter associated with the chosen command. The above-described embodiment of Fig. IC includes a description of a preferred set of predefined messages including a category termed "General commands". Other General Commands are defined by the following description: MULTIPORT COMMANDS AVAILABILITY INTERROGATION COMMAND CO c CD CO H H C H rn CO X m m H A computer transmits this command to verify that the radio channel is vacant. If another computer is already using this channel it will respond with the c Availability Response Command. If no response is received within 250msec the channel is deemed vacant. r m P: Computer address 00-03 H ιo σ> A: unit address - 00-FF H AVAILABILITY RESPONSE COMMAND A computer transmits this command in response to an Availability Interrogation Command to announce that the radio channel is in use.

Fig. 13 illustrates the processing sub- unit of the computer interface that is implemented as an add-in board installed inside a PC. Fig. 14 is the RF transceiver which is a device external to the computer and connects to the processing subunit by means of a cable. In the present application of the RF unit there are 4 transceivers each capable of utilizing two radio channels simultaneously. Referring briefly to Fig. 3, it is appreciated that, optionally, both sound and control commands may be transmitted via the MIDI connector 210 rather than transmitting sound commands via the analog connector 220. It is additionally appreciated that the functions of the interfaces 210 and 220 between the computer radio interface 110 and the sound card 190 may, alternatively, be implemented as connections between the computer radio interface 110 to the serial and/or parallel ports of the computer 100, as shown in Figs. 25 A - 25F. If it is desired to provide full duplex communication, each transceiver 260 which forms part of the computer radio interface 110 of Fig. 1A preferably is operative to transmit on a first channel pair and to receive on a different, second channel pair. The transceiver 260 (Fig. 4) which forms part of the toy control device 130 of Fig. 1A preferably is operative to transmit on the second channel and to receive on the first channel. Any suitable technology may be employed to define at least two channel pairs such as narrow band technology or spread spectrum technologies such as frequency hopping technology or direct sequence technology, as illustrated in Figs. 15A - 15E, showing a Multi-Channel Computer Radio Interface, and in Figs. 24A - 24E showing a Multi-Channel Toy Control Device. Reference is now made to Fig. 16 which is a simplified flowchart illustration of a preferred method of operation of a computer radio interface (CRI) 110 operative to service an individual computer 100 of Fig. 1 A without interfering with other computers or being interfered with by the other computers, each of which is similarly serviced by a similar CRI. Typically, the method of Fig. 16 is implemented in software on the computer 100 of Fig. 1 A. The CRI includes a conventional radio transceiver (260 of Fig. 4) which may, for example, comprise an RY3 GB021 having 40 channels which are divided into 20 pairs of channels. Typically, 16 of the channel pairs are assigned to information communication and the remaining 4 channel pairs are designated as control channels. In the method of Fig. 16, one of the 4 control channel pairs is selected by the radio interface (step 810) as described in detail below in Fig. 17. The selected control channel pair i is monitored by a first transceiver (step 820) to detect the appearance of a new toy which is signaled by arrival of a toy availability command from the new toy (step 816). When the new toy is detected, an information communication channel pair is selected (step 830) from among the 16 such channel pairs provided over which game program information will be transmitted to the new toy. A preferred method for implementing step 830 is illustrated in self-explanatory flowchart Fig. 18 A. The "Locate Computer" command in Fig. 18A (step 1004) is illustrated in the flowchart of Fig. 18B. The identity of the selected information communication channel pair, also termed herein a "channel pair selection command", is sent over the control channel pair to the new toy (step 840). A game program is then begun (step 850), using the selected information communication channel pair. The control channel pair is then free to receive and act upon a toy availability command received from another toy. Therefore, it is desirable to assign another transceiver to that control channel pair since the current transceiver is now being used to provide communication between the game and the toy. To assign a further transceiver to the now un-monitored control channel, the transceiver which was formerly monitoring that control channel is marked as busy in a transceiver availability table (step 852). The transceiver availability table is then scanned until an available transceiver, i.e. a transceiver which is not marked as busy, is identified (step 854). This transceiver is then assigned to the control channel i (step 858). Fig. 17 is a simplified flowchart illustration of a preferred method for implementing "select control channel pair" step 810 of Fig. 16. In Fig. 17, the four control channels are scanned. For each channel pair in which the noise level falls below a certain threshold (step 895), the computer sends an availability interrogation command (step 910) and waits for a predetermined time period, such as 250 ms, for a response (steps 930 and 940). If no other computer responds, i.e. sends back an "availability response command", then the channel pair is deemed vacant. If the channel pair is found to be occupied the next channel is scanned. If none of the four channel pairs are found to be vacant, a "no control channel available" message is returned. Fig. 19 is a self-explanatory flowchart illustration of a preferred method of operation of the toy control device 130 which is useful in conjunction with the "multi-channel" embodiment of Figs. 16 - 18B. i = 1, ..., 4 is an index of the control channels of the system. The toy control device sends a "toy availability command" (step 1160) which is a message advertising the toy's availability, on each control channel i in turn (steps 1140, 1150, 1210), until a control channel is reached which is being monitored by a computer. This becomes apparent when the computer responds (step 1180) by transmitting a "channel pair selection command" which is a message designating the information channel pair over which the toy control device may communicate with the game running on the computer. At this point (step 1190), the toy control device may begin receiving and executing game commands which the computer transmits over the information channel pair designated in the control channel i. According to a preferred embodiment of the present invention, a computer system is provided, in communication with a remote game server, as shown in Fig. 20. The remote game server 1250 is operative to serve to the computer 100 at least a portion of at least one toy-operating game, which operates one or more toys 1260. Optionally, an entire game may be downloaded from the remote game server 1250. However, alternatively, a new toy action script or new text files may be downloaded from the remote game server 1250 whereas the remaining components of a particular game may already be present in the memory of computer 100. Downloading from the remote game server 1250 to the computer 100 may take place either off-line, before the game begins, or on-line, in the course of the game. Alternatively, a first portion of the game may be received off-line whereas an additional portion of the game is received on-line. The communication between the remote game server 1250 and the computer 100 may be based on any suitable technology such as but not limited to ISDN; X.25; Frame-Relay; and Internet. An advantage of the embodiment of Fig. 20 is that a very simple computerized device may be provided locally, i.e. adjacent to the toy, because all "intelligence" may be provided from a remote source. In particular, the computerized device may be less sophisticated than a personal computer, may lack a display monitor of its own, and may, for example, comprise a network computer 1270. Fig. 21 is a simplified flowchart illustration of the operation of the computer 100 or of the network computer 1260 of Fig. 20, when operating in conjunction with the remote server 1250. Fig. 22 is a simplified flowchart illustration of the operation of the remote game server 1250 of Fig. 20. Fig. 23 is a semi-pictorial semi-block diagram illustration of a wireless computer controlled toy system including a toy 1500 having a toy control device 1504, a computer 1510 communicating with the toy control device 1504 by means of a computer-radio interface 1514 and a proximity detection subsystem operative to detect proximity between the toy and the computer. The proximity detection subsystem may for example include a pair of ultrasound transducers 1520 and 1530 associated with the toy and computer respectively. The toy's ultrasound transducer 1520 typically broadcasts ultrasonic signals which the computer's ultrasound transducer 1530 detects if the computer and toy are within ultrasonic communication range, e.g. are in the same room. Figs. 24A - 24E, taken together, form a detailed electronic schematic diagram of a multi-channel implementation of the computer radio interface 110 of Fig. 3 which is similar to the detailed electronic schematic diagrams of Figs. 5 A - 5D except for being multi-channel, therefore capable of supporting full duplex applications, rather than single-channel. Figs. 25 A - 25F, taken together, form a detailed schematic illustration of a computer radio interface which connects to a serial port of a computer rather than to the sound board of the computer. Figs. 26A - 26D, taken together, form a detailed schematic illustration of a computer radio interface which connects to a parallel port of a computer rather than to the sound board of the computer. Figs. 27A - 27J are preferred self-explanatory flowchart illustrations of a preferred radio coding technique, based on the Manchester coding, which is an alternative to the radio coding technique described above with reference to Figs. 8E, 8G - 8M and 10A - C.

Fig. 30 illustrates a further embodiment of the present invention which includes a combination of a Computer Radio Interface (CRI) and a Toy Control Device (TCD), 1610. The combined unit 1610 controls a toy 1620 which is connected to the computer 100 by a device, such as a cable, and communicates with other toys, 120, by means such as radio communication, using the computer radio interface 110. The toy 1620 is operated in a similar manner as the toy device 120. Fig 31 illustrates a simplified block diagram of the combined unit 1610. Figs. 32 A, 32B and 32C taken together form a simplified schematic diagram of the EP900 EPLD chip (U9) of Fig. 28H.

In this embodiment, the castle 2010 is equipped with the computer radio interface/controller 2105 which is a combination of the computer radio interface unit 2120 and the transceiver/controller 2100, both of Fig. 33 A.

Fig. 42B is a pictorial illustration of a modular transceiver/controller unit 2132. The modular transceiver/controller 2132 preferably comprises a transceiver/controller 2150 integrally formed with an interlocking toy element. The apparatus of Fig. 42B is modular in that it is configured and operative to wirelessly relay communications between the remote computer and an interlocking toy element but is not integrally formed with any individual interlocking toy element but rather interlocks with a player-selected toy structure for communication with the computer, such as a door 2134, either directly or, as shown, via intermediate interlocking toy elements 2342. Fig. 43 is a pictorial illustration of a human model figure 2400 fixedly mounted on an integrally formed interlocking stand 2410 configured to interlock with interlocking toy elements such as an interlocking platform 2420. Fig. 44 is a pictorial illustration of an interior household item 2430 having an integrally formed interlocking stand 2440 which is not part of its inherent structure. The interlocking stand 2440 is not part of the inherent structure of the table 2430. In contrast, certain interior household items, such as a refrigerator, have a rectangular base as part of their inherent structure. The stand 2440 interlocks with interlocking toy elements such as interlocking bricks 2460. Fig. 45 is a pictorial illustration of an integrally formed combination of a human model figure 2470 and a interior household item 2480 both fixedly mounted onto an integrally formed interlocking stand 2490. Fig. 46 is a pictorial illustration of an animal model figure 2500 fixedly mounted on an integrally formed interlocking stand 2502 configured to interlock with interlocking toy elements such as an interlocking platform 2504. Fig. 47 is a flowchart illustration of a preferred mode or method of interaction between a user and the computer 2110. According to a preferred embodiment of the present invention, the user is prompted or otherwise guided through the flowchart of Fig. 47. It is appreciated that the steps of the flowchart illustration of Fig. 47 may be provided in different sequences as desired. The method of Fig. 47 typically comprises two main stages: a. Build game structure (step 2506)-- Structures are built by a player using available toy elements such as controllable effect producers, electric control modules, transceiver/controller elements, and integral combinations of the above types of elements. The structures may be physically built and defined for the computer in parallel. Alternatively, the structures may be defined for the computer before or after the physical building stage. b. Generate game script (step 2508) to operate the structures built in step 2506 by programming the computer 2110. The game structure building stage (step 2506) preferably includes the following two stages each having a physical aspect and a programming (structure defining) aspect: i. Step 2510 ~ Combining toy elements into desired combinations excepting the transceiver/controller which is an essential component of any combination and which is connected into the combination in the following step 2512. Suitable screen displays enabling a user to perform step 2510 are illustrated in Figs. 48 - 50. ii. Step 2512 — Connecting the combination developed in step 2510 to specific port/s of specific transceiver/controller/s . It is appreciated that the game structure building stage 2506 may include a considerable amount of physical building which does not have a programming counterpart such as physical building of passive structures which neither control nor are controlled and such as physical building of passive components of active structures. A suitable screen display enabling a user to perform step 2512 is illustrated in Fig. 51. The game script generation stage (step 2508), in which a state machine is constructed which governs the actions of the structures defined in step 2506, typically includes the following steps: 2514 — Create new state or select existing state. A suitable screen display enabling a user to perform step 2514 is illustrated in Fig. 52. 2518 — Select controllable structures on which to define conditions and define conditions therefor. A suitable screen display enabling a user to perform step 2518 is illustrated in Fig. 54. 2520 — Select controllable structures on which to define actions and define actions therefor, in association with each of the defined conditions. A suitable screen display enabling a user to perform step 2520 is illustrated in Fig. 53. 2522 ~ Define a connection between the current state and another state for each defined condition. Connections may be from the current state to itself. A suitable screen display enabling a user to perform step 2522 is illustrated in Fig. 52 ("connect" option). 2524 ~ If the script (i.e. state machine) is complete the script file is closed (step 2526). Otherwise, the method returns to step 2514. Fig. 48 is a pictorial illustration of a screen display for the computer 2110 of Figs. 33A - 34. Using the file button 2528, the user is able to manipulate a new or existing file in which to store one or more toy operation schemes or scripts each involving one or more toy structures. A toy operation scheme is a structured set of operations, such as a conditional hierarchy of operations or a conditional network of operations or a conditional or unconditional sequence of operations, to be performed by various elements of one or more toy structures. Once the user has entered a file, the user typically defines a name for the current toy operation scheme and then performs a non- hierarchical textual selection of toy elements to participate in the scheme. In Fig. 48, the user is in the process of defining a toy structure including two different toy elements, "solenoid" and "door", and naming the toy structure "castle door". It is appreciated that the toy elements are typically named by the system whereas toy structures, including one or more toy elements, are named by the player. For example, "lighted window" is a system-named toy element which may be part of a player-named toy structure, such as "turret window", "lighthouse window", "jail window", etc., either in isolation or in combination with other toy elements such as a light sensor. Alternatively, as shown in Fig. 49, the user performs a non-hierarchical pictorial selection of toy elements to participate in the scheme. In the illustrated embodiment, the toy element images displayed to the user include a transceiver/controller-solenoid image 2530, a microswitch image 2540, a controllable human figure image 2550, a transceiver/controller/solenoid-door unit image 2560, a lightable window image 2570 and a controllable door image 2580. It is appreciated that the 6 elements shown in Fig. 49 are only exemplary of the many possible toy elements. Alternatively, as shown in Fig. 50, the user is confronted with a hierarchical display of toy elements available to him. A suitable hierarchy of toy elements may for example include the following categories and sub-categories: a. Controllable effect producers such as movable toy elements, sound production elements, light production elements. Movable toy elements may include movable human figures or parts thereof, movable animal figures or parts thereof, movable household items or parts thereof, movable vehicles or parts thereof, movable machines or parts thereof. b. Electric control modules for controlling the controllable toy elements such as: 1. Actuators (motors, solenoids, etc.) and 2. Sensors (such as microswitches, light sensors, microphones, etc.). c. Transceiver/controller elements for operating the electric control modules and the electric effect producers by means of a computer via wireless communication; d. Combinations of the above e.g. integral units including two or more of the above types of toy elements such as the integral door-transceiver/controller unit 2134 of Fig. 34, or non-integral combinations previously defined by the player-user. The hierarchical embodiment of Fig. 50, whether pictorial or textual, is particularly suitable when many toy elements are available. In the illustration of Fig. 50, the player has elected to add to a particular structure an electric control module and further has selected the type of electric control module, namely a sensor rather than an actuator. The system therefore displays pictorial images of 4 possible sensors, including a photodetector 2580, a first model of microswitch 2584, a second model of microswitch 2590 and a magnetic detector 2594. It is appreciated that the toy element displays of Figs. 49 - 50 are useful not only in selecting toy elements for combination into a game structure but also in selecting toy elements for any other purpose, e.g. in order to define an action, forming part of a state machine, or in order to define a condition, forming part of a state machine. Fig. 51 is a screen display enabling a user-defined toy structure to be associated with a particular connector-pair of a particular transceiver/controller 2100 (Fig. 33 A), 2105 (Fig. 33B), 2150 (Fig. 34) or 2160 (Fig. 34). In the illustrated example, the castle door defined in Fig. 49 is being associated by a user with connector-pair A of a transceiver/controller. According to one embodiment of the present invention, the software control is limited to only a single transceiver/controller. According to a preferred embodiment of the present invention, more than one transceiver/controller may participate in a single toy operation scheme. According to this embodiment, the transceiver/controller preferably bears a user-legible label or other marking 2136 (Fig. 41 A) which indicates to the user the name recognized by computer 2110 for that transceiver/controller. For example, in the illustration of Fig. 51, the castle door is being associated with a particular transceiver/controller whose serial number is "33335". In Fig. 51, the player indicates to the system the serial number of the transceiver/controller which he is using. Figs. 52 onward are a sequence of screen displays which allow a user to define a script or operation scheme for one or more user-selected toy structures, typically by defining a state machine for the selected toy structure/s. Fig. 52 is a screen display of a game script generated by a user including 11 states and connections therebetween. The user is able to perform any of the following operations: a. Add a new state to the state machine (Fig. 52, "new" option, which typically results in a new bubble being added to the bubble structure of Fig. 52) b. Associate a list of conditions with an existing state (Fig. 52, "conditions" option, which leads to the screen display of Fig. 54) c. Associate actions with particular conditions of a particular state, e.g. using the screen display of Fig. 52, the "conditions" option allows actions and conditions to be associated for the state which was last selected. Once the "conditions" option has been selected, the system advances to the screen display of Fig. 54. Complex actions comprising a sequence of primitive or complex actions, as well as parametric actions can be defined using the screen display of Fig. 55. An example of a parametric action is "text to speech" in which the parameter is a text and the action is producing an utterance which is an oral rendition of the text. d. Associate connections to another state with particular conditions of a particular state (typically graphically, via the screen display of Fig. 52 with respect to the connections and via the screen display of Fig. 54 with respect to the conditions. e. Delete an existing state from the state machine, typically, via the "delete" option in Fig. 52 which deletes the currently selected bubble (state) in Fig. 52. Preferably, the user can modify the features (actions, conditions and connections) of any existing state or alternatively can generate new states or delete any existing state. Fig. 53 is a screen display enabling a user to associate an action of a particular actuator with a particular condition of a particular state in a current state machine for a game in which the actuator is participating. In the illustrated embodiment, the user is associating a "stroke in" action 2410 for solenoid 2350 with a condition termed "roar detected" of a state termed "doorway". In other words, the user is designing the game such that if a roar is heard, the stroke of a solenoid associated with a certain doorway will retract and close the door. Fig. 54 is a screen display enabling the user to associate a condition on a particular sensor with a particular state (or with a particular action or next-state of that particular state) in a current state machine for a game in which the sensor is participating. Fig. 55 is a screen display enabling a user to define parameters for parametric actions. Reference is now made to Fig. 56 which shows a simplified block diagram of the computer radio interface 2105 of Fig. 33B. Fig. 57 is a simplified diagram of the interface between computer radio interface 2120 and soundboard 2124. The apparatus of Fig. 57 is generally similar to the apparatus of Fig. Λ 3 except that the MIDI connectors are omitted, such that the apparatus of Fig. 57 is useful in conjunction with sound-boards or computers which lack MIDI connectors. Fig. 58 is a simplified block diagram of computer radio interface "2120. Fig. 58 is generally similar to the apparatus of Fig. Λ 4 except that the MIDI connectors are omitted, such that the apparatus of Fig. 58 is useful in conjunction with sound-boards or computers which lack MIDI connectors. Fig. 59 is a simplified flowchart illustration of a preferred method allowing one of the computer radio interface 2120 and the computer 2110 to receive commands over the audio channel, rather than over the MIDI channel, from the other one of the computer radio interface 2120 and the computer 2110. The method of Fig. 42 first detects whether an audio signal is currently arriving and if so, detects whether the audio signal is audio information (i.e. the contents of an utterance which one of the toy structures' speakers is supposed to emit) or a command. This is preferably effected by detecting whether or not a command-characterizing preamble has been received. The command- characterizing preamble typically comprises SYNC followed by SQ signals as described in detail below with reference to Fig. 59. Fig. 60 is a diagram of analog and digital representations 2300 and 2310 respectively of the following signals: SYNC, SQ, zero-valued bit and one-valued bit. The frequencies and time durations of each of the above signals are as follows: SIGNAL FREOUENCY TIME DURATION SYNC Hz 0.5 msec SQ 500 Hz 2 msec zero 1 Hz 1 msec one 666 Hz 1.5 msec Preferably, more than one audio channel connects the sound board 2124 and the computer radio interface 2120, and typically a first audio channel transmits audio signals from the sound board to the computer radio interface and a second audio channel transmits audio signals in the opposite direction. Figs. 61A - 61E, taken together, comprise a detailed electronic schematic diagram of a preferred implementation of the apparatus of Fig. 58; and Reference is now made to Fig. 62 which is a pictorial illustration of an assembleable toy house, built from interlocking bricks and including interior household item models fixedly mounted on stands which interlock with the structure of the house. It is appreciated that, for users having a relatively low level of playing skill, the screen displays of Figs. 48 and 51 may be eliminated if the toy structures employed by the user are configured in accordance with a pre-defined design. For example, in Fig. 33, an interlocking building block set may be purchased with assembly instructions explaining how to build a castle and a roaring duck of the configurations illustrated. It is appreciated that the apparatus of the present invention is adaptable for any interlocking toy element having an electronically controlled functionality such as motion, sensing capabilities, illumination and sound generation. The pictorial illustrations of the interlocking toy element are not necessarily to scale. It is appreciated that the software components of the present invention may, if desired, be implemented in ROM (read-only memory) form. The software components may, generally, be implemented in hardware, if desired, using conventional techniques. It is appreciated that various features of the invention which are, for clarity, described in the contexts of separate embodiments may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment may also be provided separately or in any suitable subcombination.
