Here I showcase an interesting way to visualise music with a kind of fractal/psychedelic hologram effect using my 3-color laser projector system using a WiFi speaker system and an old reflective anti-static bag used to ship electronics! And no better music to visualise with such a system than the inventive and idiosyncratic music of the great Richard Feynman. Enjoy the patterns made by marimbas, congas and his famous bongo drums in this rare series of recordings!
