Here is a video of the finished installation.

What happened

1. Build the monolith with single addressable mapped LEDs
2. A webcam mounted under the ceiling
3. Object track a random visitor
4. Project an anamorphic circle on the surface of the monolith for this visitor
5. Provoke some dude to blow it up

Design

Positions of the LEDs where defined beforehand with an Inkscape SVG drawing. One large side and one small side is driven by one Raspberry Pi. A laptop is running the server components which sends over OSC a vector of RGB8 values to the raspberries, which then drive the leds.
