Thanks, Zee! That's a
terrific video. I'm impressed and would love to talk with someone who has stuff like that going on in his head. I also want to know how long it took for him (them?) to do it. It looks like very many days. And many gallons of paint. Note how the white paint becomes grey as he repeatedly paints over it. The website has a lot of interesting art work you might like, too, including many walls like these:
