We are not sure who this guy is but it looks like he has a bad day. The Head-in-Jar 3D Prop features a 3-d head trapped in a closed jar. Not only has he been separated from his body but his skull has been opened to reveal his brain. His eyes are wide open like he is looking at you. We don't know who put him there or what they learned from dissecting him but we know he is creepy.
