Gaming PCs ship with RGB lights that do one thing: rainbow. Forever. Like a screensaver that got a job.

So I made mine pay attention.

rgb-mood has two moods, and it picks on its own:

Music playing: the lights pulse with the bass of whatever comes out of the speakers. Spotify, YouTube, a game. The color drifts slowly around the rainbow while the beat does the punching.

Quiet for a few seconds: the lights glow by the hottest chip in the box. Blue when it's cool, purple when it's working, red when it's cooking. It breathes faster as it heats up.

RAM: stays solid blue, or flip one setting and it turns into a VU meter.

How it works, Tim Urban style: the PC listens to its own speakers (PipeWire), a bit of math (an FFT, via numpy) pulls out the bass 30 times a second, and OpenRGB tells the lights what to do. When it's quiet, it reads the CPU and GPU temperatures instead.

It only runs when I say rgb-mood on . Nothing starts at boot.

Honest status: tested on my RAM and motherboard lights.…
