Spektrum, a collaborative piece with Ceci Navaro-Sanchez and Kelin Kaardal, is an interactive colour mixer console and Processing program. Using visual tropes of traditional painting and a deployment of physical computing, this project was born. Created within Processing, we attached three accelerometer knobs to an Arduino Uno and fed them into CNC-machined knobs atop the physical console. An optional physical reset button, to clear the screen, is also included. We are looking forward to its usage in collaborative projection art scenarios or gallery spaces alike. Spektrum is an experimental homage to the Memphis Milano technological future that never happened.
