Designs by HumansDesigns by Humans is exactly what it sounds like. Tshirt designers submit the design, site users vote on what they like and the winning designs get sold on the site. Most probably DesignsbyHumans is a ripoff of the Threadless concept (which also boasts some damn cool tees) but seems to me like Designsbyhumans has a voting userbase who appreciate the aesthetic cool rather than the humorous design. Definitely holds a little more class than the usual tshirt sites you come across, at least in my book.
