Choice Project
For my choice project I use Google Sketchup to 3d model. I plan to 3d print this puzzle I designed. The cubes are suspended inside the box and can be manipulated from the outside. However the sliding door in the side of the box means you can only see one box at a time. Couple that with there being only one correct way to assemble them and many incorrect ways (courtesy of the extra places to attach them to each other) it makes quite the puzzle.
