(unfinished) Ballad...Curtain/Motor Demo Video May1st

So I settled on servo motors instead of steppers.  They are lighter, cheaper (I have a bunch from a previous piece anyway), robust, and easy to wire (no driver chips needed, just ground, power and pwm control signal) and stronger than they look.  They don't turn more than 180degress, but it doesn't seem to matter yet.  I had trouble getting the steppers to work with their drivers being controlled by the Arduino.  Although I didn't give it a true "college try"-- the other drawbacks (weight, cost, complexity) was more important to my decision.   In this demo I've set up a Wii-remote to control their position.  This will be a tool used by a performer (mezzo-soprano, singing a solo, channeling Elena Emery).  When the "curtain room" is not in use by performers, it will be a installation, controlled by sensors (passive infrared and or ultrasonic pulse) monitoring  audience members and randomly reorienting while it plays back the audio/video content.
