For those of you with an iphone or ipod touch there are a couple of apps that will work for you. One is free and is just Roulette Free, from Maui Media Lab. It's just the roulette wheel, the European version (one 0). The other roulette app I like is the World Roulette app, it is the full fledged game and has both the European and American Wheels. Though it is the full game it can be easily used for the randomizer.
