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.)
