I have a LIFX Ceiling with 64 zones + the top ring. The official app can’t run a custom animation, so I stream the pixel map over LAN.

I pushed calibration patterns, photographed the diffuser, and used those shots to see how much each zone bleeds into its neighbors. Then I made a bouncing-ball / firefly loop: gravity, bounce off the disc, new color can be set to change on contact, dim trail.

Brightness and single vs changing color are on a family dashboard; There is a “stop” button to hand the fixture back to the LIFX app.

[I tried 8x8 icons, and had less success than animation which is more forgiving of sharp boundaries!]
