Computer controlled lighting display synchronized to music

During the 2005 Christmas season, electrical engineer Carson Williams set up a Christmas light show in the garden of his house. The lights were synchronized to the song, and the show was free for anyone passing by who tuned to specific low-power FM frequency on their car radio.

A three-minute video of the show circulated widely on the Internet, and also spawned many others who imitated the style of setting their Christmas lights to the song. It was later adapted by Miller Brewing Company into a 30-second TV advertisement for Miller Lite that aired on U.S. stations in late 2005.[1]]

Carson wasn’t the 1st to do this but his video spread through the Internet like wildfire and ignited the industry and hobbyists all over.
