Came across this interesting post on Hackaday....
The shop I go to still has one.Continuing with pole terminology, doe anyone remember Barber poles? Long cylindrical red and white swirly things that spun inside a glass cylinder - that's how you knew where to get a hair cut. There must be some left out there spinning away.
I had a cat that done that one time. Amazing how far it fell straight to the ground, and didn't appear hurt.
