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.
@teekenng Drawing with a laser pointer on a record that I covered with glow in the dark vinyl. The laser energises the phosphors in the #photoluminescent vinyl causing it to glow. As they lose their charge the older lines fade creating the trail effect. #hypnotic #vinylart #laser #spiral #liveanimation ♬ Space Walk – Lemon Jelly
