Click on any of the pictures to see them "in action" (large files, though)

We drew fancy pictures on balloons, popped them, and then tried to "flatten out" the pieces to recreate the pictures without any distortion. We found that it is impossible to recreate a picture from a curved surface (the inflated balloon) on a flat surface (the popped balloon) without altering it in some way - just as all flat maps must have some intrinsic error built into them. Cool.
