I am a huge fan of Threadless. A website which allows users to submit designs for t-shirts. Users can score every submitted design and the t-shirts with the highest scores are then sold on the site. Some designs are truly outstanding for example this one. But they have no chance against the new dynamic t-shirts developed by Phillips. They call the technology lumalive and can read more about it here. Take a look at the video and you can see why these t-shirts are so special.
