Abstract:
1. A toy building system comprising: building elements with connectors for releasably interconnecting building elements; and a first function building element with said connectors, the first function building element including: at least a second function building element with said connectors, the at least a second function building element including: wherein the first function building element is configured, in addition to performing the first controllable function, to forward, via the light emitter, visible light encoding the second control signal to the second function building element, wherein the second control signal is determined as at least one of (i) an output control signal as a function of the received first control signal, (ii) a delay of the received first control signal, (iii) a repetition of the received first control signal a predetermined number of times, and (iv) the received first control signal meeting a predetermined condition, and wherein the function building elements are connectable with building elements other than function building elements so as to form a toy structure such that each function building element is positioned within the toy structure spaced apart from and without direct physical or electrical contact to other of the function building elements, the function building elements configured to interact with one another by means of only the control signals.
