"I don't know if anyone has built an equivalent computer with modern tech. I'd be interested to see how small it could be built." Now there's an app for Google Glass!

I'm really interesting in roulette. I wrote a Python script that plays online roulette (mainly to learn Python, don't actually expect it to make money.)
