This isn't the usual "sound-reactive LEDs" you've seen for years.
Emotiscope was built by @lixielabs from the ground up as an open, powerful bridge between sight and sound that produces very unique and pleasant-to-look-at light shows which synchronize to your music without any visible latency whatsoever, with a show that’s reactive to notation, vibrato, tempo, and more.
A magic diffuser covers 128 of the world’s smallest addressable LEDs, which are being refreshed at up 450 FPS. Emotiscope doesn’t look like a screen, it looks more like some kind of neon-gas display from the far future or recent past.
