i just figured out the symbol here is a brain draped in a chess board and felt a slight twinge of disgust seeing this extracted organ (perhaps i watched too many horror movies in my day) I would suggest a cute little smiling proud yellow cartoon figure something like a cross between a smiley and an et with an oversized head suggesting brainy as a replacement. Then as you accumulate brains you could put a whole row of them on one line or even make them different colors to show different quantities. He/she can put its hands on its hips to emphasize the proud look. Perhaps a whold slew of these brainys can be created as per the smileys. I think the light deprecating humor of the chess brain idea will then be more tastefully presented and so enhance the site and lose the slightly weird current look. Just trying to be helpful and hope I don't hurt anyone's feelings.
