“When we explain it to people we get a lot of doubt,” Matt Parker says of Lumarca, his volumetric display installation, which renders graphics in 3D and has been in the works for several years. What puts that doubt in people’s heads is not necessarily how brilliant it looks, but instead how it works — Lumarca is composed of little more than a computer, a projector, and some string. Projected images turn hanging bits of string into dazzling beams of light, which can create 3D objects that appear to be suspended midair. It’s this contrast between the futuristic-looking display and the low-tech construction that makes people wonder. “Part of me, every time we build one, expects it not to work this time,” he says. “So I guess I’m not surprised when other people don’t believe it when they see it.”
