Very cool, and very nice work! Question about the tile: it looks like you added some finish to the top, covering both the tile and the grout. Is that polyurethane, or some other tile sealer? I really love the shiny...me like a da shiney!
It's an epoxy flowcoat called Envirotex. I've heard it compared to 70 coats of polyurethane but you pour it out in one application.
