I'm on the younger side, and this project was my first real introduction to the possibilities of computing. It let my grayscale iPod Classic play videos and Doom, which at the time, was mindblowing to me and my middle school classmates. In the process I was fortunate enough to actually learn a thing or two about Linux and computers in general.
