Dr. Mark Csele is a professor at Niagara College. Just found this page covering some of his past Halloween displays. In his own words:
Our 2008 display, pictured here, featured a skeleton in an electric chair. When a kid approaches the porch the system triggers and the skeleton rises out of the chair accompanied by fog, a strobe light, and loud sounds of an electrical arc. The front window featured a rear-projection video of a large tesla coil operating with large arcs streaming everywhere to complete the ‘mad scientist’ appearance….The electric chair has a light rope for the “wires” connecting the skeleton to the chair. Upon triggering fog is released by a fog machine behind the chair, illuminated by eerie green light and a strobe light.
Nice work, doc! Have you seen our 2009 Make: Halloween Contest? (Hint hint.)

Glad you liked the project.
I like the idea of the contest, but it’s not open to Canadian residents (Sorry, I’m from the “Great White North”, eh?)
And there is a PIC controlling the whole thing. The IR sensor uses two laser beams to detect an onlooker and an old 16C84 pic. Various other displays also use PICs to control timing, etc. for the display (easier than using a bunch of discrete relays and timer modules).
Cheers!
