Optoisolated xmas light control

[buzzkill] brought this crazy christmas light controller to my attention. The hack is pretty neat. The potiometers in several standard dimmers were replaced with photo-resistors. When squares of the screen are lit, the dimmer is activated. In essence, it’s a cheap optoisolator for controlling AC power. The software that generates the interface appears to be sound actuated once it’s programmed by the user.
