A set of springs lit by bright LEDs.


Lots of metal springs, connected with sensors and LED rings in between form a hexagonal grid. It’s modular construction allows for large scale installations; the soft- and hardware are both carefully built with scalability in mind. Two Teensy Arduinos control the in- and outputs, with an additional python API and simulator running on a computer providing easy modding and opening access to other developers.


The controller is being built as a platform to run different interactive animations and games. I am experimenting with several games at the moment, some fast and arcadey, while others are more abstract and slow.
