Via Matrixsynth, the Furby Gurdy:
Inventor Nervous Squirrel explains:
Each furby has 4 controls: mute, crash, loop and reset. The handle turns 8 cams which operate corresponding microswitches to create interesting rhythmic patterns. Part of the ‘setting up’ section at the beginning has been fast forwarded. Please commission me to make lots more of these machines!
Hang in there ’til the furbies gets revved up. It’s actually rather beautiful.
