I do like Cliff. This reminds me, I dropped my bottle last year; time to replace it. If Klein bottles catch your fanvcy, there's another and very different artist doing metal and glass algorithmic artwork in 3D printers: Bathsheba (at http://bathsheba.com http://bathsheba.com). I had Cliff's bottle sitting on top of her laser etched known universe cube at work. Each contains the other. Too bad nobody there gets the joke. But I saw the same combo in a documentary about String Theory, in one of the scientists' office, so I'm not alone :)
