I’m linking to this simply through sheer amazement. It’s a bbc story about a graffiti artists whose images move. He paints a wall, takes a picture, and then repaints again and again to gradually build up a moving image. It’s basically a form of animation, but a slow, methodical one. The beeb calls it ‘The most painstaking art in the world’. They’re probably right to say that – some of these images can only be appreciated from space, over days. I’m just in awe of the patience and creativity involved in generating such beauty.
