Can't think of a better gift for an artist friend. Buoy Brush – Painting Brush by Weijie Kong. They simply float vertical in a bowl of water, making sure you don’t stain the tabletop. The sizes easily distinguish the brushes and look artsy too!
Epic Floor Design, although I'm not sure what the idea is. if laid with clear or glass tiles to see the design would be different, but to put black tiles over doesn't make any sense. I wonder if you get a magnifying glass to view the floor.
