I extended the nice spiral tool with noise and ramp for the frequency of the loops and a ramp for the amplitude.

There is an issue though. When you apply the filters, the loops often don't complete the 360 round.
I like this unplanned feature, but I also would like to have a more regular spiral…

If anybody want to try to fix it or play with it, I've attached the hip file with the embedded custom spiral tool.
