Or at least I heard he sweeps it up to use again. He was at Union Square last week. I passed seeing the sparkling sand twinkling in the gloaming. The artist is Joe Mangrum who has created prints and book documenting the mandalas. It was fascinating to watch, mesmerizing like a Zen garden. He's received a lot of attention including the prestigious Lorenzo de Medici award in "New Media", for his striking piece, "Fragile." Catch him if you can, before it's swept or blown away.
