Natthakit Kim Kang designed and built and incredible interactive LED installation, Click Canvas.

The project was developed to display at Yolo House, a creative space and gallery in Bangkok.  The installation features 187 LED boxes in a 17 x 11 grid that change colors when users press them.  It uses a Teensy 3.6 to control 2,244 LEDs.
