Some time back I came across Assembly Chess on Raspberry Pi (without any OS) and today I managed to get this done and finished. I am impressed, it is well implemented, and just worked straight out of the box.
At least I found some decent use for an empty iPhone 3GS box - you could fit the Raspberry Pi in there as well.
I had some wonderful moments like when I was playing with LEGO as a kid... thank you Xu, Bora and Gun!
