The “Creepy Cat Robot” is a stuffed cat with servos and photo-resistors stuffed within its body. A photo-resistor poked into its stomach signals whether or not two servos stuffed into its arms should wiggle around or not, based on a certain light threshold.
The experience involves giving a volunteer a flashlight and instructing them to walk into a darkened room. When in the dark, the cat will “dance”. However, when someone tries to look at it with the flashlight, the cat will stand still. This creates either a humorous or horrific experience for the viewer, depending on the context.
