From Muppet Wiki

The Floating Face is a character that has come to be known as "Nobody" (for his appearance: he has no body) and "Limbo," which are the names of two separate sketches in which he has appeared. The character consists of two eyes and a mouth made of string, and is controlled by invisible wires attached to gloves worn by two puppeteers. The puppet is performed live in front of a prerecorded film that is projected, layered or composited.
