I love Christmas light displays!  With the advances in technology and programming capabilities, they just keep getting better every year.

If you're not watching it already, check out ABC's Christmas Light Fight show.  The houses they feature will blow your mind, like the one above.

Tom BetGeorge, a music teacher, built the massive guitar and keyboard and even has certain songs that the keyboard will play the notes along with as part of his display.  The above video features music from every geek's favorite movie Star Wars and even has a light saber duel!
