For anyone looking for a cheap, interesting way to decorate a blank wall (I'm looking at you, college students), look into rasterbation. You heard me. The Rasterbator is an amazing online tool that quickly transforms an image of your choice into an easy-to-print format, allowing anyone with a basic printer and computer paper to create posters of any size. My new dorm room currently has bare walls with high ceilings and I found this to be a very cool way to fill up the empty space. At the moment, I'm working on having Stephen Colbert's massive visage tower over me as I sleep.

If you're still not convinced, check out this huge gallery of the hundreds of walls that have already been improved by rasterbation.
