"Threadless is a community-centered online apparel store run by skinnyCorp of Chicago, Illinois, since 2000. Co-founders Jake Nickell and Jacob DeHart started the company with $1,000 in seed money after entering an internet t-shirt design contest.
Members of the Threadless community submit t-shirt designs online; the designs are then put to a public vote. A small percentage of submitted designs are selected for printing and sold through an online store. Creators of the winning designs receive a prize of cash and store credit."
The T-Shirts are amazing. And if you buy them then you'll be fairly unique amongst your friends. I have about 12 now - the service is very good. I know Emma is a fan, too. ;-)
