This project was for a gift exchange, so I couldn't share it until now. It's a (large!) laptop bag/backpack with 100 LEDs in the front flap arranged in a Fibonacci spiral (inspired by @jasoncoon ) and diffused through a Voronoi arrangement of 3D printed translucent black PETG tiles.
@geekmomprojects I love this. It's like dinosaur hide (I imagine).
@ancientjames thank you! It does have a very nice feel to it.
