I love the new concept! I never would have thought of a propeller head. I like the darker colors on the smaller hat better than the "shaded" colors on the larger hat. Also the shadows look off. I see light over dark on the power button too, but the hat is sitting up there without a shadow. Do you see what I am saying?
Also, what if we moved the power button to be the U in cubicle?
Another idea, what if we lost the power button and used the two e's on geek as eyes and put the propeller hat over it?
