Optical illusion - Murray the tracking Skull

thingiverse

Optical Illusion - A Tracking Skull "Murray" appears to be following you with his eyes and head. Check out the animation below, which takes a few seconds to load. This entire effect is based on a pretty simple principle but it's impressive nonetheless. The skull can be mounted on a wall like a picture or placed on a desk. I've also designed a stand that allows for direct illumination of the skull using an LED, which amplifies the effect significantly. Scale both models to your desired size and print easily (printing the skull upright will likely yield better results).
