Instead of plastic skeletons that blow over in the wind, this loads four looping spectral animations onto a DVD. Projecting the Sinister Spinster onto sheer window curtains actually looks eerie from the sidewalk. The catch is needing an old-school DVD player or optical drive to get it running, but the illusion beats static yard props by a mile.
