I took Sniderman's advice and brought the Old School Rocks image to CafePress to make a t-shirt out of it. I really want to wander around NTPRGCON in a t-shirt with the logo on it. The boy, of course, needs one too.
Or, if you want to do it yourself, I'll give you a copy of the 600 dpi colored version so you can go use your own t-shirting facilities. It's YOUR picture, after all. Honestly - I suck as a capitalist. My heart just isn't in it. :)
