Sorry if this is a double post. I shared this from mobile, and then had someone tell me it didn’t show up in the FastLED community.

I wired up a stereo MSGEQ7 board and added a couple of music reactive patterns.
I switched to a thinner section of 2.5" PVC pipe, which makes the spiral taller and provides more distance between the LEDs and the frosted glass for better diffusion. I also added a rolled sheet of vellum paper inside the glass for even more diffusion.
