BLU is one of the most enticing street art and design groups around today. While their website is a little overdone in the DIY conceit, they have some amazing work on it. Particularly this awesome collaborative animation with David Ellis, and other videos I urge you to see here. (Also, check out Print‘s 2008 interview with Blu here.)
You should also sample BLU’s book of drawings (pictured above and below). BLU has a rich display on their website of murals they created in Berlin, Modena, and Milano, among other international locales.
