Piment Noir have been working on music visualization with RGB LEDs and Micah Elisabeth Scott fadecandy framework. The work is focused on making a very natural visual rendering on 3D printed semi-translucent shape out of 2D LEDs PCBs. Or how to trick our 3D world with light propagation inside matter almost like the arrival of photography have historically done. The Proof of Concept code made with processing is already in our github and we're sure you will enjoy it.
Our future plans is to make a larger Art installation.
Preview demo vidéos are available on my youtube channel.
