I am a little late to the party, but I am jumping on the *awesome idea* wagon. Since I read all three pages at the same time, I would like to make a suggestion on the design Inferno did about three posts above this one.
Without the GP shield to capture your interest, perhaps you could:
(1) incorporate the angled bar shape concept from thread 11. The shape, though wider at the bottom, would be a subtle counter to the eyes of the Geek Mech Mascot.
(2) Make the blue border edge heavier, to also pull the warrior in. and
(3) not sure on this last suggestion, it depends on what your intent was for the mech head expanding past the border (definitely like that). Originally I was going to suggest also adding in a little blue line on the head shape, since it fades into the white page. However, the more I look at it, if you did the other changes, it should stay like it is. The blending in could be a hint at the GeekPolice ability to track down bad things, no matter how they *blend* into the programming.
I hope one of you feels like making one along those lines, for us lowly users. (lurves on the blue and aqua and prepares to kidnap the Geek warrior to help promote GP on other sites).
