Nice one!
I do like the black one, though I'd really like to keep that hat, and also it might be a bit "dark" for some people. Bryan made a valiant attempt with the white hat, but I don't quite think it'll cut the mustard.
I've checked in your white background one and it's looking pretty good. At some later stage I'll definitely provide some options from the admin config page but for now this will do.
Thanks all and especially Eloy!
