Spread Firefox is running a worldwide T-shirt design contest for upcoming Firefox 3.
On phase 1, which runs until March 16, competitors will enter their designs by uploading them to Flickr, tagging them as “FF3 Tcontest”, joining the FF3 T-shirt Design Contest group and adding their designs to the pool. Everyone will be able to see the entries as they are posted to Flickr. Five designs will be selected by Mozilla and will pass to phase 2.
On phase 2, people will vote for their favorite design from the 5 finalists to choose a winner, who gets her design added to the Mozilla Store catalog, a T-shirt with the winning design and a $250 Amazon.com gift card. The four runner-ups get $50 amazon.com gift cards and T-shirts.
