One of my hobbies...weird but very cathartic!

Too cool Damien! Not in the man cave for me though, I'd put em on the front verandah!

Never imagined they are belt driven.

Love your artistry! Yes most 'moving head' fixtures use ratio belt drives to run the pan and tilt functions. These work well to achieve smooth sweeping motions and very accurate XYZ positioning, however 'scanning' type fixtures usually mount a mirror directly onto the pan/tilt stepper motors. This gives fast movement of light using the mirror as opposed to a moving head fixture...ah now i feel all warm and fuzzy, i can tackle Tuesday!

So cool, way out of my league though, I've just seen them from time to time and checked out the source (as you do). However, I like your description of 'fast movement of light', (I assume you probably mean fast deflection) but I like the implied idea that the speed of light may not be constant.

Intended or not this is always a fun muse for me, chuck the rules out and see if one can up with a different idea of how everything hangs together....Hmmmn, now just one more beer and I'm sure I might work it out...lol sleep,nope,still dumb lol!
