This glowing pendant reacts to sound, creating a dynamic light show. A video is below, but it can’t show all the detail. The pendant reads the audio levels and updates 3,000 times per second while the video is only at 30 fps. All this in full 24 bit color. An advantage of using LEDs instead of screens is they can update so much faster. No screen you’re looking at can convey the vividness of this light display. You must see it in person.
