Black Box Lightshow flickers its LEDs to the beat

Darren Murph

Nah, the Black Box Lightshow won't welcome you home, do your laundry or keep you updated on scores around the league, but it will keep your eyes fixated when connected to an audio source. The unit was reportedly based on a design conjured up while Rosendahl was still in college, and it basically emits a LED lightshow by "displaying the top half of the waveform of each channel with their zero levels in the center." The two knobs on the left control the amplitude and the sweep speed, and of course, the bass notes tend to have the most noticeable effect. Hypnotic, indeed.
