Physical Output Device for Spectrum Analyzer

Here’s another cool project by Taichi Inoue- a Physical Output Device for Spectrum Analyzer. It came out way back in 2007, however the effect is beautiful, and this is the first time I’ve seen it. I’ve been trying to think of creative projects to do with an oscilloscope that I picked up a couple of months ago, and it seems like building an interesting visualizer such as this would be a great place to start.
