I'd go with the cog. Personally, I'd go with the cog, but xerox it a bunch of times, then blow it up with the xerox, then decrease it, so it just becomes a collection of dots (obviously, you can do this in photoshop with far less work/money, but xerox is totally diy punx rawk, d00d), but you know, that's personal preference. I like the cog idea in general, though.

Anyway, that's my two cents.
