This light sculpture by German multimedia design collective lab binaer may look like a persistence of vision (POV) display at first glance, but in fact works on a very different principle. It’s built from a record player, and the turntable has been treated with a phosphorescent pigment. Messages are printed on the pigment by an array of bright lights on the tone arm, and slowly fade to black as the phosphorescence wanes. It’s titled »Spiel mir das Lied vom Tod« or “Death calls the tune.” [via Hack a Day]
