At Make:, where I found it, they call it "a Mesmerizing video" and I would agree. Watch for 8.54 minutes as Janez Jevnikar "Sprayman" creats a piece of "science fiction art" using only spray paint. In Sweden we might call this Hötorgskonst* and that's not, generally, a flattering description. But this is fun to watch!
* Hötorget is a square in Stockholm where similar kinds of "art" was/is? sold. Konst is art.
