I'm not a fan of the huge brain thing. It takes up space, slows down page loads, makes it difficult to browse the site on mobile devices, and looks ugly. Highlighting main topics of interest is a worthy goal, but your graphic is a poor solution.
P.S. I am guarded by an elite cadre of zombie pirates. Your ninjas stand no chance !
What if the front page looked a little more like this?
