Wow – I think strolling by Mark Gervais’ Hallowindow animation would definitely scare the heck out of me. Just watching the spiders in this clip was a lil’ trip to creep city (population: me).

He sells a DVD of the above sequence on his site for such decorative haunting, but one could do a lot with a projector hooked up to a video camera – perhaps a little face paint and a flashlight, and you could be host to a giant speaking head in your window, interacting realtime with incoming guests. freaky chic!
