Oh my goodness this made me cry a little. People are so creative.
From the yahoo music blog:
"Using stop-motion animation (with absolutely no computer graphics or effects), more than 700,000 vintage Lite-Brite pegs, and the help of 83 friends who'll probably never want to look at another Lite-Brite peg for the rest of their lives, the David Crowder Band created the video over the course of 2,150 hours and 148 pizzas. They literally made things with light, and the result--a 2D tale of true love--is electric indeed."
