It is no parlor trick: There is a skull and, in the dark, it is glowing. Somehow it is now floating above us all. Listen: The skull is speaking. It is saying your name. It knows about you and your favorite flower and all about your tenth birthday. But it does not matter. You are not convinced. For some reason, you are still full of doubt. You stare into the dark, looking for wires. Grasping for strings, you hold your hands out.
