It’s been circulating the web for about ten days now, but if you have yet to view the latest work by Blu, take a few minutes to check out the clip below. An artist practicing and living in Argentina, Blu is pushing graffiti and street art to new levels by creating animations on walls and sidewalks. And with Muto, it could certainly be called an artistic and technical tour de force: by creating the animation it meant he couldn’t have more than one frame in existence at a time, with no possibility of reworking old frames or sketching out new ones. Once the frame was shot, the work was destroyed.
