Its kinda interesting to critically watch the rotational plane of a
brightly lit (daylight) propeller against a dark background, as someone
else varies the engine RPMs. I've seen the blade tips move like 1/2
inch out of plane at certain bad rpms.
Or a variable speed party strobe...
Sheds an interesting light on things like that.
