Caught a link to this on a friend's blog, VERY amusing/impressive/OMGWTF. The Griswolds would be proud.
(A word of caution, the video is family-friendly, but the site... is, umm... very male-centric, if you catch my drift. I'm not going to click on any of the links to find out whether they're work-safe or not, but just to be on the safe side, view this from home.)
Make sure the sound is on.
I'm guessing the owner of this house must be involved in theatre, because I can't imagine who else would have access to the kind of computer program necessary to make this happen (not to mention a lightboard!)
