I know there are other ways to do this, but they wouldn't allow one/open up the possibility of using all the power of a clone, i.e. putting more stuff and functionality inside the clone.
The patch feeds its results and indices back into the clone, so basically creating a 2 dimensional until/for-next loop. The result is with one value, for example the 0-360 slider, you can change 3 values.
Not sure of the practical purpose, but "seeing" it was enough to motivate me to make it.
I hope you are having a great day. Stay healthy.
Peace through sharing.

p.s. I had been thinking about the electromagnetic field of the Earth and what it does when it spins, which I think this emulates very well.
