Walking Art Video: Mesmerizing Animated Wall Painting by the Artist Blu

I enjoy this animated wall painting from the artist Blu. I also like Blu's website, not only for its clever design but for the sketchbooks.
I haven't sketched in a long time. I usually sketch outside, but it's too cold, and I'm getting cabin fever. I get vicarious pleasure from watching Blu's walking/sketching on the walls, something I know I can't get away with at home.
