This guy (Gavin) built a physical version of the same music visualisation spiral. Fixed at 12 notes per octave and no ability to act as input. He feeds it with MIDI from a standard keyboard.

That whole blog is amazing. It ends in 2023?
Gavin Smith is a pretty interesting guy. I've talked to him and gone to a presentation by him (we both live in Sydney), but I wouldn't say I know him. He's still active. Perhaps he's too busy making stuff to write about it?
I know that feeling, my blog usually gets attention when I don't have a soldering iron in my hand :)
