Haunted house run using home automation gear

We've always thought our basement full of old Newtons and Amiga machines was pretty spooky, but we'd admit that we've been one-upped by Pennsylvania's Halloween Park, which built an entire haunted mansion using off-the-shelf HAI home automation equipment. Designed by Digital Panacea, the system is "run by typical motion detectors, contacts, resets, and timers," which trigger spooky sound effects and mechanical effects, including a leaping ghost nicknamed Dead Fred. That's way more interesting than the usual home-automation setup, we'd say -- any of you planning on re-rigging your systems at home before the kiddies come by?
