Using an INSTEON PowerLinc Modem, sold separately, you can program custom lighting sequences that allow you to turn your lights on and off and also fade them up and down according to the music of your choice. You can specify an unlimited number of show “events” that can span minutes, hours, days, or even years.
Here’s a link to a video (WMV) of Light Show Master in action. It’s not as impressive as those Metacafe videos down below (after the break), but you are free to improvise. May be your light show will win an Oscar. 😉
