Tetrahedral Light Forms Respond to Viewer’s Physiology #PiDay

Here’s a beautiful installation piece by Jamie Zigelbaum. Each bioresponsive illuminated tetrahedral form contains a Raspberry Pi noir camera — via Creative Applications

Created by Jamie Zigelbaum and commissioned by Design Miami/ Basel, where the project debuted earlier this year, Triangular Series is a site-specific lighting installation composed of numerous, truncated tetrahedral forms. Each object has an unique form and senses the other and the physiological rhythms of visitors beneath them.

Each ‘light form’ includes a downward facing RaspberryPi noir camera with an IR led array running of an rPi. On board, software incorporates simple computer vision for blob tracking to know when someone walks directly beneath a light and their velocity. This velocity becomes a parameter in the system and effects the internal respiration setting for that light — the oscillation frequency of their brightness. When a person walks below a light it flashes warm white (from cool which is the default) and sends a radial wave of warmth through its neighbors. Bigger lights send a bigger wave, the largest covers the entire space. A slow walker will slow the respiration, fast will speed it up.
