Remove the coin from the egg shape
Entered into the design competition in Osaka, Japan, July 2010. This puzzle is made out of Corian which is a versatile material used in many commercial products. The object of this puzzle seems easy enough. Just remove the coin. The problem is that you cannot see what is happening inside the egg shape. Due to the handmade nature of this puzzle, there may be imperfections. The solution of the puzzle is still the same.
