I have a software product that I am developing and will be releasing. I love how Google names their Android releases after confectionary ("Cupcake", "Eclair", "FroYo", "Jelly Bean", etc.) and thought about a similar model. I am stuck on one minor problem:

What list of items to use.

I don't want to (and can't) use Android's system, and I want something that sounds cool and, ideally, nerdy. Has anyone got any ideas?
