Since only the 'skin' on the outside is opaque, I figured out that if you take a diamond burr to it, you can strip it off and light it from the outside. This is getting closer to what I want.

I'm going to need some brighter LED strips.

Lighting it from the middle is neat, but not great in the infinity mirror setup. (Also, I promise it looks better in pictures than it does in reality!)

Still trying different things - haven't landed on something that really works yet.

That's definitely going to need to be brighter - it's also hard to take a video of!

Oooh - put a thermal camera on that and see if it's a good inductive heating element!

It's mounted on a ESP-S3 that is programmed to show up as a HID keyboard. Board and code here: github.com/illumneo/cap...
