Abstract: A fold out display is particularly adapted to support a wide variety of different types of group work activities, team projects, and the like, and includes a free standing base which fixedly supports a primary panel having an exterior display surface. At least one foldable panel is hingedly supported on the primary panel for movement between a closed folded position overlying the primary panel, and an open unfolded position protruding outwardly coplanar with the primary panel. The foldable panel includes at least an interior display surface which overlies the display surface of the primary panel when in the closed folded position. A one-piece living hinge has opposite side portions connected with the side edges of the primary and foldable panels, and is shaped such that when the foldable panel is shifted into the open unfolded position, the two display surfaces are juxtaposed in a substantially contiguous relationship to collectively provide an enlarged generally continuous and uninterrupted display.

Abstract: A drawing game board comprising a cover board which is fastened to a drawing board by mating hook and loop pile fastener material. The surface of the drawing board which is hidden by the cover board is made of erasable marker board. The cover board has six doors, which, when opened, reveal portions of the erasable marker board underneath. Drawing game boards are distributed to each of six players. Each player draws part of a body on his drawing board and then passes his board on to the next participant who will then draw the next body part without being able to see what the first participant drew. Thus in round robin fashion the participants will draw an entire body, and, at the end of the game, the drawings will be displayed in full for a few laughs. This game is designed to instruct young children in drawing the parts of the human body while amusing them.

Abstract: A thermochromic drawing device is disclosed which can be marked and erased by selectively changing the temperature of its drawing surface. The drawing surface of the drawing device consists of a flexible substrate printed with thermochromic inks having at least two color states. The flexible substrate has low thermal mass thereby enabling it to readily assimilate temperatures induced by a user and, consequently, facilitating the transition of the thermochromic inks from one color state to another. The drawing surface is further provided with an insulating layer which isolates the flexible substrate from unwanted heat sinks and heat sources thereby preventing unwanted color transitions of the thermochromic inks. Thus, a user can selectively change the color state of portions of the drawing surface to create distinctive markings.

Abstract: A writing device is disclosed wherein a clear overlay is pivotally attached to an underlying enclosure. A support surface is formed on the enclosure beneath the clear overlay. Paper forms may be placed on the support surface such that one may write on the clear overlay, using the written guide to trace.
