Stand out in the crowd with a Cocoa tee-shirt. I've a few more ideas that I will convert into products when I get a chance.

You can buy this one from Zazzle. It has white lettering with the code [self setNeedsDisplay:YES]; on the front and the back. You can pick any dark color shirt you like. I get a cut of the proceeds.
