I think it looks pretty good. It's pretty unique looking, and it directly relates to both games (via programming and binary and all that) and uncountability as a concept. The logo is basically a stylized depiction of the Diagonal Proof, which is a way of proving that an infinite set, e.g. the set of real numbers, cannot be counted, because there's no way to match up every real number with a corresponding natural number (counting number). That's where the name "Uncountable Games" comes from.
