deviousStill, this is but a prototype, thrown together in a couple of hours based on a premise. Working with it a while will give me more ideas, I'm certain. I think though what I'm heading for is a full-on rail-mount system, which is in that far-off but nice category that I have reserved for the carrot-on-the-stick to actually finish a film project. Sort of a self-fulfilling prophecy: in order to justify the purchase or manufacture of some more exotic piece of filmmaking toolage, I need to have tangible proof of my growth and exploration as a filmmaker publicly available.
I'll post a clip on YouTube if I can get permission. Tomorrow is a busy day.
