Came across a very cool t-shirt site called Threadless. I had been about to set up my own shop at SpreadShirt, so I could upload my own designs and get professionally printed custom t-shirts. But that all seems like more trouble than it's worth, so I think I'll leave the designing to the "professionals" (or at least amateurs with more time and talent than me). Threadless is more than just an online t-shirt shop, of course. It's very Web 2.0, as an ongoing interactive t-shirt design competition, blog, and more. Very nice community atmosphere and a constant stream of new designs coming in all the time. The successful designs get printed for a limited time, which also makes the designs more collectible. You can vote on which ones you like, and ask for re-prints of out of print shirts. I really want this polar bear shirt (it would be great to wear to our seminar on global change in the Arctic), so get over there and request it.
