Is that a SAD lamp?
To be honest, it's an accidental lamp. I didn't have many free GPIO pins on that ESP32 development board, so I needed to push some of the entropy bits though pins that were also assigned to an RGB LED.
The flashing light was giving me a headache, so I put a diffuser over it.
It flashes different colors wildly. Because of the nature of the underlying signal and it's varying frequency, this looks pretty cool if you put a rolling-shutter camera (like on a smartphone) really close to it.
