I like the energy of the icon, I think the yoyo may not need to be stylized so much - the word is a little absurd as it is, I don't know that we need to bring it out too much extra
like the yoyo font in entry 14, maybe loose the brain image, and relax the "brain" font into something more subtle....I would be interested in seeing it on a solid color background - something not hugely loud...
