I would like to use a sound track to dim a string of Christmas lights (ie: the volume is inversely proportional to the light intensity, though I can deal with the reverse). I have a scary-terry set up and a dimmer, but the servo is too fast, so it is all or nothing. I want a slow pulse with some erratic stuff thrown in the mix. Any ideas? I would like to do this on the cheap and this is my first venture into the whole animatronics thing (scary-terry is as complex as I get right now).

"On the cheap" and dimming AC can be... well, scary (and dangerous). There are simple circuits on the net that convert 120 VAC to DC that you can run through a power mosfet; that mosfet can be driven through an opto-coupler that takes your audio input. Be careful -- AC bites hard.
