The original tEp House Show!
This was from back in 2005, when we put up christmas lights on the outside of our house and made them all respond to music. We piped the sound through speakers in the coal chute so that you could hear it on the street as you walked by, and each individual light (plus the inflatable penguin) were controlled from a giant relay board.
Little did we realize that without the cover on the coal chute, the deep cave would get super cold, a pipe would freeze, and all the speaker equipment would get ruined. Well, cool while it lasted!
