Hmmm...what is Threadless? User-designed t-shirts? Oh: "...here's how it works: designers that feel like releasing some energy can come here and design a tee shirt. Design for the sake of design ... no corporate project guidelines or branding or anything, just a design that would look funky on a tee shirt. Submissions are posted on the site to be rated, and the best ones are printed. The designer will get a few tees for free, and their design will be sold to the world from the site, for mega-cheap prices." Interesting. And very nicely designed. I bought an assembler.org t-shirt for $9 (plus $5).
