Laser Pointer x Glow-in-the-dark Record
Compact discs use a laser to read data and convert that to music. Vinyl records, on the other hand, use a needle to pick up vibrations. Artist Tee Ken Ng used a laser pointer to do something else with a record, exposing a glow-in-the-dark record to laser light as it spun on a turntable. He made some more complicated patterns in this second video.
