I met Benjamin Gaulon when he was a student at the MA Interactive Media & Environments in Groningen. I was teaching there. His graduation work was the RES, a multi-player musical instrument using the classic Nintendo controllers. It was a highlight of Sonic Acts XII in 2004, and we had much much fun playing it. He’s now based in Dublin and has almost finished a new version, using Arduino, and has released the source code, and will shortly also get the PD code up. So you could build it yourself…
