These are a lot of fun:var. 0 - chromatic - 48 tines:
In three minutes, the largest dot will travel around the circle once, the next largest dot will travel around the circle twice, the next largest dot three times, and so on. The dots are arranged to trigger notes on a chromatic scale when they pass the line.
Details here. Also cool: Wheel of Stars.
This puts me in mind of old Vincent Price movies, I don't know why.
Now I know how music composers of 70s sci-fi movies and the BBC Radiophonic Workshop did their work.
Also the composer for the 1969 documentary Moonwalk One.
That is both visually and aurally awesome.
Oh wow, thanks for posting this. I've been trying to find it again for years.
