An apparatus, comprising a handle of a captive but freely-moveable wand, the handle useable to move an attached wand viewfinder over a clear front window of a front component to selectively reveal parts of printed matter on a hidden back component, wherein the clear front window has semi-transparently printed matter thereon, wherein inside the apparatus, a concealed component tethered to the wand is selectively moveable between the semi-transparently printed matter and the printed matter on the hidden back component, and wherein the tethered concealed component has an opening that lies in alignment with a matching opening in the wand viewfinder so that, with selective movement of the tethered concealed component: (a) both the printed matter on the clear front window is shown superimposed over the selectively revealed parts of the printed matter on the back component in the wand view finder and (b) solely the semi-transparently printed matter is shown on the clear front window outside the wand viewfinder.

Full Description:
BACKGROUND 
     There are a few “magic window” devices which permit the combining of an obscured printed image with a superimposed image printed on a transparent substrate. Such devices lack flexibility and versatility. A problem is that they are not particularly effective in engaging a user. 
     SUMMARY 
     What is needed is a “magic window” device that, by giving the user more freedom of operation, adds an interactive surprise effect such that it becomes puzzling for the user to understand how such an effect can be carried out under the interactive control of the user. By allowing the user to manipulate the device more fully, e.g., by allowing control of motion, orientation, and position of a viewfinder, the resultant interactivity and user control accompanied by surprise and puzzlement would exhibit a truly “magical” quality and lead to a more delightful user experience. 
     For example, according to teachings hereof, an apparatus is provided with a captive but free-floating wand with a viewfinder at an end of the wand, the viewfinder moveable over semi-transparently printed matter shown on a transparent top part of the apparatus, wherein inside the apparatus, a concealed part of the apparatus is tethered to the wand and travels with movement of the wand between the transparent top part and a hidden bottom part of the apparatus, wherein the tethered concealed part blocks the hidden bottom part from view except through an opening in the concealed part underlying the viewfinder so that movement of the wand shows both the semi-transparently printed matter and opaque printed matter on the bottom part superimposed in the viewfinder. 
     Such a device can be used as a premium item, a greeting card, a direct mailer, a point of sale display, a magazine insert, as part of a packaging application, or any number of similar printed applications.

     DETAILED DESCRIPTION 
       FIG. 1  shows a front view of an embodiment of an apparatus  10 , according to the present invention. The apparatus  10  may be produced as a standalone “magic window” device or may be combined with other component parts, such as shown in  FIG. 3 , to form various novelty devices that incorporate an apparatus such as disclosed herein. 
     In the embodiment of  FIG. 1 , a front panel  12  of the apparatus  10  provides a frame or border  14  surrounding an opening  16  for presenting a printed transparent window  18 . For instance, a transparently clear, 4 mm sheet of Mylar material may be cut to size larger than the opening  16  and glued or otherwise fastened to the back of the front panel  12  as shown for instance at reference numeral  18   a  in  FIG. 6 . It then serves to function like a pane of glass though which the user may be provided a view into the apparatus. Printed matter on the transparent material  18   a  may for instance be a head and shoulders profile  20  of an attractive young woman as shown (in outline) which may be provided in color, such as printed matter in the form of a reproduction of a color photograph. The photographic effect may for instance be carried out using a halftone reprographic technique that simulates continuous tone imagery through the use of dots that vary in one or more of size, shape, or spacing. Use of other reproduction methods to produce the printed matter is of course possible. The manner of printing of the printed transparent window  18  may be such that the printed matter is itself transparent or semi-transparent. Thus the printed matter, e.g., the exemplary colored profile  20  may be printed in such a way that it is not opaque to the transmission of light. When depositing a thin layer of various color inks onto a transparent Mylar sheet, for instance by use of a halftone printing process, the resultant printed matter is naturally transparent to the transmission of light. The various colors (for instance include yellow, magenta, cyan, and black) may be deposited as various sized, shaped, and spaced ink dots. The printed matter may also include line art. 
     Behind the front panel  12  is a back panel (not shown in  FIG. 1  but see reference numeral  48  in  FIG. 6 ) with printed matter on at least one side. The back panel may be made of high quality paper board such as Solid Bleached Sulfate (SBS) stock used for high end packaging where the quality of any printed image is required to be at a high level. The front panel  12  may also be made of the same high quality SBS stock. The at least one side of the back panel with printed matter faces the back of the front panel  12 . The printed matter on the back panel may be sized and positioned to match the size of the opening  16  in aligned registration therewith. Or it may be slightly larger to avoid showing any surrounding white coloration from the surrounding unprinted paper board near edges of the window. When depositing a thin layer of various color inks onto the back panel sheet, for instance by use of a halftone printing process onto the bleached white surface of SBS stock, the resultant printed matter is naturally opaque to the transmission of light. The various colors (for instance include yellow, magenta, cyan, and black) may be deposited as various sized, shaped, and spaced ink dots. The printed matter may also include line art. The back panel may itself be sized to match the size of the front panel so that they are in matching size alignment when folded over onto each other into a parallel, layered relationship. The front panel and the back panel may be foldable parts of a same piece of SBS stock such as shown by the respective reference numerals  12   a ,  48  in  FIG. 4 . 
     Importantly, the printed matter on the back panel “corresponds” to the printed matter on the printed transparent window  18 . Such correspondence may take many different forms. For instance, a boldly printed (halftone black &amp; white) x-ray profile of the head and shoulders of a human skeleton may be provided underlying and in registration with the colored profile of the attractive young woman presented in the halftone printed transparent window.  FIG. 10  (not to scale) shows the outlines of such an x-ray profile. In practice, as previously mentioned, it might be printed with a black and white halftone reprographic technique to simulate the continuous tone of an actual x-ray image with a range of greys. The “correspondence” is in this embodiment the more or less overall registration of the color profile with the x-ray profile. It should be realized that the x-ray illustration of  FIG. 10  is sized to match the profile of  FIG. 1  so the registration of the two profiles may be carried out so as to achieve the color profile of  FIG. 1  in overlying alignment with the grey tone x-ray profile of  FIG. 10 . In this way, the opaque black &amp; white printed matter on the back panel may be seen through the transparent colored printed matter within the viewfinder. Another correspondence example will be shown below in connection with  FIG. 6  but others are of course possible, limited only by artistic imagination. 
     A magic wand  23  is provided with a viewfinder attached to the end of a handle or tab  22 . The viewfinder may be square, rectangular, circular, or any other desired shape. The magic wand resembles a magnifying glass with a handle, and as such, the magic wand attracts the user&#39;s attention by in effect inviting the user to grab the handle  22  and move the viewfinder which, the user will discover, is free-floating in a plane parallel to the front panel. The tab or handle  22  of the magic wand  23  may be attached by an appendage (not shown) through a slot  25  in the front panel  12  to a concealed opaque panel  24  (see  FIG. 2 ) lying under the printed transparent window and above the printed matter on the back panel  48 . The opaque panel  24  may be made of SBS stock without any printed matter, e.g., it may be bleached white in color with no printed matter thereon. Under the control of the user&#39;s movements  26  of the wand  23 , the concealed panel  24  may be made to likewise move in any planar direction  26 , i.e., by controlling movement of the handle or tab  22 . Thus the concealed opaque panel  24  is made to travel or slide in a narrow planar space between the printed matter on the printed transparent window  18  on front panel  12  and the printed matter on the bottom panel. If the opaque panel  24  is completely devoid of printed matter (e.g., completely white), its movement (tethered to the movements of the magic wand) under the profile  20  will not be visible to the user. Because the concealed panel  24  is smaller in size than the front and back panels, it may even be rotated to some degree depending on the relative size difference. Such rotation of the magic wand  23  is about an axis perpendicular to the plane of the front panel. The user may simply tilt the handle  22  slightly in an up or down lateral direction and thereby exert a twist force on the handle and appendage or tab  22   a ,  22   b . A narrow field of view  28  of less than the totality of the field of view of the printed matter on the back panel may be provided through a viewfinder on the end of the wand  23 . That narrow field of view helps contribute to the illusion of a “magic window” frame or in the case of  FIG. 1 , a “magic x-ray window” frame around an opening  30  in the concealed opaque panel  24  and through the semi-transparent printed matter on the printed transparent window  18  that overlies the concealed panel  24 . In moving the narrow field of view of the viewfinder about within the wider field of view of a scene represented by the printed matter on the back panel, the user gets to search with excitement and delight for possibly multiple hidden surprises awaiting. The term tab is also used to mean any appendage attached to the concealed panel  24  and the viewfinder so as to be useable for pulling, pushing, or otherwise maneuvering the concealed panel  24  in any planar direction parallel to the front and back panels. As shown in  FIG. 4  below, the concealed panel  24  may itself provide a complementary tab extending from a side thereof for attachment to the tab  22  of the wand  23 . An appendage for passing through the slot  25  may instead be provided separately. Or, the tab  22  may include an appendage for passing through the slot  25  and attachment to the concealed panel or to a tab thereof. Any such appendage or tab or combination thereof should be sufficiently rigid to be able to move the concealed panel in concert with the user&#39;s movement of the handle or tab  22 , i.e., without undue slack so as to create a unified impression that the viewfinder on the end of the wand  23  and the opening  30  are one and the same even though they are not actually connected in the vicinity of the viewfinder (since they lie on opposite sides of the printed transparent window  18 ). 
     In various embodiments, the degree of transparency of the printed matter of the printed transparent window  18  may be controlled in relation to the degree of visibility required of the underlying printed matter on the back panel through the semi-transparently printed matter on the printed transparent window  18 . The correspondence between the printed matter on the back panel and the printed matter on the printed transparent window  18  may include printed matter on the back panel that is visible directly, i.e., not seen or to be viewed through parts of the semi-transparent printed matter but merely seen in some relation or correspondence thereto. See for instance the forest animals and cartoon character in  FIG. 6 . In this way also, the printed matter on the back panel may graphically “correspond” to the printed matter on the printed transparent window in a way that perplexes the user as to how the hidden matter can be exposed by simple movement of the magic window about in a planar motion, under the user&#39;s random volitional control, to produce a surprising, humorous, or amusing effect for the user. 
       FIG. 3  shows a perspective view of a novelty device that includes an apparatus, according to an embodiment of the present invention. In the illustrated novelty device, a rectangular sheet of paper board (see  FIG. 4 ) such as high quality SBS stock is folded to form a plurality of overlapping panels. The particular novelty device of  FIG. 3  incorporates an apparatus such as shown in  FIG. 1  by means of a sheet such as presented  FIG. 4 . The novelty device is shown standing upright on a horizontal surface such as a tabletop. As shown, the novelty device has four overlapping panels, one of which is not visible in the illustration because it is folded within two other panels. The hidden panel corresponds to the back panel described above in connection with  FIG. 1 . The front facing panel  12   a  in  FIG. 3  corresponds to the front panel  12  of  FIG. 1 . An openable panel  32  (see panel  32   a  in  FIG. 4 ) is operable to be opened as shown unfolded from a folded state, i.e., swung open about a fold line  33  or axis defining a corner  34  so as to be made apart from the front panel  12   a  and the back panel that are fastened together, e.g. glued together to form front and back panel parts of the illustrated apparatus (as in  FIG. 1 ). It should be understood that the openable panel  32 , though useable in many products, is not necessarily present. Nevertheless, for novelty devices such as shown in  FIG. 3 , a user may swing the openable panel  32  of the novelty device about the fold line  33  along the corner  34  to the open position as shown to allow the novelty device to be stood upright on the tabletop as shown or to allow for a reading of a greeting or the viewing of other graphic matter printed on the part of openable panel  32  facing the front and back panels when in the folded state. The surface of the openable panel  32  may for instance have printed matter thereon such as a greeting card type message, graphics, or both. For example, for the embodiment of the apparatus shown in  FIG. 1 , a novelty device might be provided with the symbolic work of art as shown on the front panel of  FIG. 1  as the front of a greeting card with a humorous message printed on the openable panel  32  intended for an epicurean friend. 
       FIGS. 4 and 5  together show parts that may be assembled into a device such as the novelty device of  FIG. 3 . 
       FIG. 4  shows a rectangular sheet of paper board with four panel sections separated by vertically scribed fold lines that serve for ease in folding the panels into overlying relationship during assembly. A front panel  12   a  has a central opening  16   a , a slot  25   a , and top and bottom folding tabs  40 ,  42  that fold along respective scribed fold lines  44 ,  46 . A back panel  48  is folded (downwardly into the plane of  FIG. 4 ) and all the way around (one hundred and eighty degrees) so as to be aligned with the front panel  12   a  with printed matter on its underside appearing within the opening  16   a  and in registration therewith. In other words, if looking down over the top edge of the sheet, the panel  48  is rotated 180° clockwise about an axis defined by the scribed line  50  so as to lie in parallel facing the back of the front panel  12   a . The front panel  12   a  is then parallel to the back panel  48  and the printed matter on the back panel  48  is visible through the front panel opening  16   a . As shown in  FIG. 6 , the back panel  48  may have printed matter on at least one side as shown at reference numeral  28   a . In particular, when folded over, the at least one side with printed matter  28   a  faces the front panel  12   a  and is aligned with the opening  16   a  in such a way that the printed matter on the transparent window panel is in the desired correspondence with the printed matter  28   a  on the back panel  48 . For instance, the alignment may be such that the trees printed transparently or semi-transparently on the transparent window panel  18   a  in  FIG. 6  are aligned with and overlie the boldly printed trees in the printed matter  28   a  on back panel  48  so that the transparent trees exactly match the underlying boldly printed trees. In this way, the user is presented with the two separate printed matters as a unified one printed matter. The woodland animals and the cartoon character appear on the printed matter on the back panel only but are nonetheless presented in this example in spatial, perspective, or at least positional “correspondence” with the printed tree matter on both the front panel and the back panel. 
     A clear, printed transparent window panel  18   a  is shown in  FIGS. 5 and 6 . It is glued or otherwise attached to the back of front panel  12   a  so as to be affixed behind the opening  16   a . After assembly, it is thus situated between and parallel to the front panel and the back panel and is immobile with respect to the back panel and the front panel. The panel  18   a  may be made slightly larger, e.g., 3.5 inch×4.5 inch (88.9 mm×114.3 mm) than the opening  16   a  (e.g., 2 9/16 inch×3 7/16 inch (65.1 mm×87.33 mm)) to provide extra space for overlap of peripheral edges on the backside of panel  12   a  for ease in gluing. As described previously and as shown in  FIG. 6 , the transparent panel  18   a  is provided with transparent or semi-transparent printed matter (trees shown printed faintly with transparency) on at least one side that corresponds to the printed matter (corresponding trees and woodland animals and cartoon/goblin character printed on the white stock so as to appear opaque on the at least one side of the back panel  48  and overlies same with exact registration so as to align at least parts (e.g. trees) of the two sets of printed matter. The printed matter  28   a  may have overall dimensions greater than that of the opening  16   a  as shown in  FIG. 6 . Thus, when folded over, the at least one side with printed matter  28   a  faces the front panel  14  and is aligned with the opening  16   a  in such a way that the printed matter on the transparent window panel is in the desired correspondence with the printed matter  28   a  on the back panel  48 . As shown in  FIG. 6 , the alignment may be such that the trees printed transparently on the transparent window panel  18   a  are aligned with and overlie the boldly printed trees in the printed matter  28   a  on back panel  48  so that, from the perspective of a user viewing the front panel through the magic window  23   b , there is no perception of there being two sets of printed trees because the transparent trees match the underlying boldly printed trees and are seen as one set of printed trees. 
       FIG. 4  also shows a wand  23   a  with a handle or wand tab  22   a  attached to a wand viewfinder  23   b  (“magic window”) at the end of the wand. A concealed panel  24   a  is also shown with an opening  30   a  and a tab  22   b  extending therefrom. After the above-described 180° foldover of the back panel  48  onto the front panel  12   a  so as to be in parallel alignment therewith, the concealed panel  24   a  may be inserted in the planar space between the folded over back panel  48  aligned with the front panel  12   a.    
     The tab  22   b  extending from the concealed panel  24   a  may have two sections  22   c ,  22   d  separated by a foldline  22   f . Prior to insertion of the concealed panel  24   a  between the front panel  12   a  and the back panel  48 , a first section  22   c  of tab  22   b  may be attached directly to the concealed panel  24   a . This may be done by folding the first section  22   c  over at a fold line  22   e  and gluing it to a facing side of concealed panel  24   a  shown in  FIG. 4 .  FIGS. 6 and 7  each show the first section  22   c  folded over and glued to the concealed panel  24   a . As shown in stylized  FIG. 7  (not to scale), tab  22   b  will then be able to serve as a “stop” at the fold line  22   f  against excessive extension of the wand in the direction of the arrow  70  in  FIG. 7 , and prevent possible tearing damage to the connection between the outer tab  22   a  and the underlying hidden inner tab  22   d , when the wand is fully extended. This “stop” acts to signal the user to stop trying to extend the wand any further and thereby prevents the connection between the outer tab  22   a  and the inner tab  22   b  from being damaged by the wand  23   a  being pulled out too far with excessive force. During assembly, the second section  22   d  of the inner or hidden tab  22   b  is slipped through a slot  25   a  and glued or otherwise attached at least at an end thereof to the outer or visible tab  22   a  of wand  23   a  as shown in  FIG. 7 . After connection, the hidden inner tab  22   b  and the outer visible tab  22   a  become a unified tab or “tab assembly” or assembly of appendages that may be grasped by a user as a handle of the wand  23   a  to move the visible viewfinder  23   b  outside the apparatus and the intermediate panel  24   a  hidden inside the apparatus as a unified whole. As shown, the first section  22   c  of the inner hidden tab  22   b  may be shorter than the longer second section  22   d.    
     In  FIG. 6  the magic window and tab  22   a  may be seen directly and in silhouette through the transparent or semi-transparent printed matter from the rear through the panel  18   a , as viewed from the backside of the front panel  12   a . During assembly, after the concealed panel  24   a  is put in place between the front panel  12   a  and the back panel  48  and is tethered to the magic wand  23   a , the panel  53  is folded over by a counterclockwise rotation about the fold lines  51  and the two tabs  40 ,  42  may then be folded over and glued to the panel  53  to enclose the apparatus. The vertical pair of scribed lines  51  allow the panel  53  to be folded over without a sharp corner so as to provide a little extra space (depending on the distance between the scribed lines  51 ) on the corner edge and thereby avoid the panel  53  pressing down too hard on the facing front and back panels when the panel  53  is folded over and glued tight on the other side. This allows the panel  48  after it is folded over to face the rear of the panel  12   a  (as described above) with sufficient space to allow the concealed part  24   a  to move freely in the planar space between the two panels  12   a ,  48 . 
     Upon assembly of the apparatus, the concealed panel  24   a  thus serves as an intermediate panel parallel to the front panel  12   a , the back panel  48 , and the transparent panel  18   a . The concealed, intermediate panel  24   a  is situated for lateral travel in a sliding motion between the transparent panel  18   a  and the back panel  48 . The concealed, intermediate panel  24   a  is smaller than the front panel but larger than the opening  16   a  in the front panel. In an embodiment as shown in  FIG. 6 , the concealed, intermediate panel may for instance be provided with dimensions of 4 inch×5¾ inch (101.6 mm×146.05 mm). The intermediate panel is visible through a 2 9/16 inch×3 7/16 inch (65.1 mm×87.33 mm) opening in the front panel, the intermediate panel blocking visibility of the printed matter on the at least one side of the back panel except that the intermediate panel has a 1⅜ inch×1⅜ inch (34.925 mm×34.925 mm) square opening that is smaller than the opening in the front panel and that exposes a part of the printed matter  28   a  on the at least one side of the back panel  48 . The overall size of the assembly for the described embodiment, as measured from the front panel, may be 5 7/32 inch×7 27/32 inch (13.26 cm×19.92 cm). 
     The tab  22   a  connected to the intermediate panel  24   a  is moveable  26  by a user in moving the intermediate panel to expose different parts of the printed matter  28   a  on the at least one side of the back panel  48  through the opening  30   a  in the intermediate panel  24   a . The intermediate panel is moveable between the transparent panel  18   a  and the back panel  48  in such a way that the opening  30   a  in the intermediate panel  24   a  is moveable within the boundaries of the opening  16   a  of the front panel  12   a.    
       FIG. 8  shows a die cut pattern in solid lines for a die usable for cutting one or more preprinted sheets, e.g., 29×23 inch paper board sheets (73.66 cm×58.42 cm), e.g., one SBS stock sheet with a die cutting machine or press. Before or preferably simultaneous with the cutting operation, an impression die may be used to impress a plurality of fold lines  84 ,  86 ,  88  separating a plurality of foldable panels  90 ,  92 ,  94 ,  96  on each sheet as well as other fold lines for the various tabs as shown in dotted lines and more fully described above in connection with  FIG. 4 . Or, the fold lines may be scored with a scoring instrument. The die cut pattern may provide for cutting parts for only one or even more than the two devices shown in  FIG. 8 . The illustrated die cut pattern is used to cut preprinted parts from one sheet for assembling two devices, such as described above for instance in connection with  FIG. 4 , each device also including a separately preprinted clear transparent window  18   a  as shown for instance in  FIG. 5  made of a Mylar sheet. A die cut press  102  or top platen shown in  FIG. 9  is able to cut the illustrated pattern from a sheet or a stack of sheets  104  set on a table, bottom platen, cutting surface, or area  106  by pressing for instance a steel rule cutting die  101  onto the sheet or sheets  104  to create a plurality of multiple panel parts  80 ,  82 . The die  101  may be in the form of a flat base or substrate or block made for instance out of high-grade and high density plywood, e.g. a hardwood made out of maple that is free from voids and imperfections. A bandsaw or laser cutter may be used to cut precisely positioned slits into the substrate. A hardened steel in the form of an elongated razor blade (“steel rule”) is cut and bent by a die-maker and inserted into the slits in the substrate. The steel rule thus assembled in the slits forms thin metal walls held in place in the slits. The edges on one side of the steel rule may have a selected bevel that is sharpened for cutting the SBS stock on the press machine&#39;s bottom platen or table  106 . The other side faces the top platen or press  102 . An ejection rubber pad may be adhered to the substrate of the die to help eject the SBS stock after it is cut. Altogether the walls of the die  101  form a steel rule die that is pressed onto the paper board or boards to do the cutting operation. As suggested above, the die is attached to the top platen of the die cutting press that provides the force required to make the cut. The SBS stock is positioned below the die and then the press is actuated. The cutting edges of the steel rule penetrate through the SBS stock until they come in contact with the bottom platen or table which may be made of steel selected for cutting the SBS stock. The press then reverses and the cut part is exposed. As suggested above, foldlines, creases, perforations and the like may be made with a special rule that is positioned on the same die as the cutting rule. It is also possible to have a secondary foldline die positioned on the opposite side of the press and aligned with the primary foldline rule to create very crisp foldlines or creases.
