What I'm listening to today: "Everything is a synthesizer", Kurti
This musician rigs an electrical engineering learning tool (a "SystemTechnik Type 3910 Digi Board 2"— various standard chips + banana plugs) to make a repeating buzzing sound they control with switches, and combined with a Monotribe (first of the current era of desktop grooveboxes) builds a surprisingly catchy dance rhythm. They let this run for one minute, then burst out laughing and turn off the camera.
