In case anyone is interested I made some Apollo TShirts based on community input and they are now for sale. They were "home made" on a screen printer I have and they are made on a per order basis.
Check 'em out: http://scalenine.com/blog/2007/03/22/apollo-tshirts-now-available/ This may be the beginning of something I do every month or two, get community feedback/suggestions on t-shirt designs based around developer interests, make them and sell them. Stay tuned.
