I just finished my second tutorial about how to make a Simon Says game for the arduino, but what makes this game special is that you use an SNES controller! Go check out the tutorial at Instructables.com and leave a comment!
Nearly 4 years ago, I built an ipod out of spare parts from ebay. I wrote most of the tutorial on how to do so at that time, but I never got around to finishing it or publishing it. As of yesterday, the tutorial can be seen for free online on Instructables. It is a pretty easy build, and I learned quite a bit from it. Good luck!
