My worksite for my newest concrete pot outdoor scrap-mosaic creation is as messy as any creative art-site could be.  Just stones, jewels, tile, junk, spacers, dirty rags, water, trowel, sand, ants-bugs, and dirt everywhere.  I think the rush comes from sitting in chaos trying to create order from that which is a temporary mix of chaos and order so that if just enough order is actualized, just enough to fool people into thinking there IS actually order in the universe while there really is none.
