I could probably be that judge X-D :-P
But seriously, I'd be willing to judge (though I think you're looking for mods, one of which I am not). I'd love to be a part of the contest, but I guess I'd probably actually satisfy the "...doesn't know jack shit about sprites..." criteria mentioned by uzo. I don't know where or how one would even start to make a sprite, so I don't expect I'll get to participate in the actual designing of sprites, unfortunately. I might know enough to be an okay judge though.
