More venues for the artistically inclined

So, maybe you're not the most talented person in the world, but you still yearn to have your work displayed, on a t-shirt perhaps.  You can't draw, but you have a vision comprised of the work of others, and some witty and clever text.

Perfect!  Use Spreadshirt, an online t-shirt printing company that allows you to choose from a bank of graphics, and write in your own text.

Another example of do-it-yourself identity.  For others, check out the Mongolian Shoe BBQ from Puma, where you can build shoes directly suited to your taste.
