Awesome! This guy is adding a Mac Mini to his car - putting the power button on the dashboard, using a touchscreen monitor also built into the dashboard... way cool. The post to which I've linked, plus a few of the following posts, detail his adventure. It doesn't even seem like posts about this amazing computer-car are finished. Keep looking at this site and dream about what it would be like to make this stuff.

If you really care about knowing what that all means, you either know the code already, or you can get it decoded for you here.
