I'd like to see smart visuals for the combination candy + genius. There is the option "cartoony character" in combination with a nicely flowing script font. Another one would be a clever way to express that with a more abstract concept - take a look at the brainy muffin example I've attached. In general, I'd like the logo to be in a compact format, maybe on a badge. Think food label with a retro touch. The logo should work well on a squared space (thumbnails for user profiles on social networks).
