Abstract
A kit for creating a flat folding projection device is provided and includes a lens and a sheet defining at least a first, second, third and fourth panels, each panel separated from the other panels by at least one fold. A hole is positioned in the first panel, the hole defining an edge. A cut is positioned in the first panel adjacent to the hole such that the first panel on either side of the cut can be separated to create a space configured to receive and hold the lens therein. Further includes is one of: a light source, a translucent sheet or a light source and a translucent sheet. An envelope contains the foregoing such that a thickness of the envelope is less than ½ inches.

A flat folding projection device comprising:
- a sheet defining a plurality of panels, each panel separated from the other panels by at least one fold;
- a hole positioned in a first panel, the hole defining an edge;
- a cut positioned in the first panel adjacent to the hole such that the first panel on either side of the cut can be separated to create a space configured to receive and hold a lens therein;
- a second, third and fourth panels;
- an adhesive configured to join the first, second, third and fourth panels in a continuous loop such that when joined, the first and third panels are adjacent to the second and fourth panels;
- a plurality of flaps extending from the first, second, third and fourth panels, each of the plurality of flaps separated from its respective panels by at least one fold the flaps configured to fold relative to their respective panels to create a bottom and a top to define a closed space between the bottom, the top and the plurality of panels;
- said plurality of flaps and the plurality of panels are configured to fold between flat and unfolded positions such that in the unfolded position, the first and third panels are opposite and facing one another and in the flat position, one of the at least one fold that separates two of the plurality of panels is at approximately a 180 degree fold such that two of the plurality of panels adjacent to each other are facing each other;
- said third panel positioned opposite the first panel in the unfolded position and said third panel having a cutout configured to receive a translucent element such that an object image exterior to said closed space is projected on the translucent element.
