Ruckingenur II is the Reverse Engineer game! From the same people that brought you Silicon Foundry.

I've always had a hard time explaining how much fun it is to tear something apart, and figure out how it works. It's a weird type of entertainment and engagement to try to get across to non-technical people. This game is BY FAR the most fun game in the category, and it really gets the idea across. It takes a little bit of technical know-how to get into, but anyone who has programmed anything should be able to pick it up, and play with it a bit.

Now, if only they had an iPhone version of the game....
