When we were in Honolulu about 8 years ago, we were wandering the streets and came upon a guy doing the same sort of thing. At the end, we bought the painting he was doing at the time and it is hanging on the wall behind me. He then showed us his gallery. He called it "Art in Motion". If you are in Honolulu some time, it is worth a look.
