Puzzle of Evil

Inspired by a Khan Academy Engineering blog post, I set out to make make a copy that I could take to the office. http://engineering.khanacademy.org/posts/evil-puzzle.htm

This puzzle has 2 sides, one is decptively harder than the other. Both are the same outside dimensions so they can be glued together.
