Arch, it would be a shame for the artistic community to lose your
contribution in this area. I suggest you go shopping for a strobe
light--not the kind that goes on a camera; I mean the kind that flickers in
synchronism with a rotating thing. I'm serious. I have an old strobe I
could probably get working, and I would be happy to try it in this
application if it would be any help. If you adjusted the strobe to a nearly
synchronous speed, the object would appear to rotate slowly, so you could
avoid all the dangerous ends.
