Artist Jonathan Schipper has built some fantastic sculptural creations, including this enormous sphere of television monitors. The scale is impressive: 800 pounds, 215 monitors, and 215 cameras, making the displays into fragmented electronic mirrors. The result is, of course, far from invisible as this gothic-looking technology rolls around a gallery floor. (Don’t miss the video on his site.)
