"Treehouse of Horror VI", the latest installment in The Simpsons' popular Halloween specials, features Homer3, a parody of a memor able episode of "The Twilight Zone" in which a young girl passes through a wall and is trapped in the 4th dimension. In the climatic moments of "Treehouse of Horror VI", Homer accidentally steps into the third dimension while desperately trying to avoid his sisters-in-law, Patty and Selma. Having lived his entire life in the 2D world, Homer enjoys his new depth until, through a minor mishap, he creates a black hole which threatens to engulf the entire universe. Bart alone is brave enough to cross over into this other world, in an attempt to save his father. The story is replete with inside jokes poking fun at computer animation. Computer-generated backgrounds are filled with quirky mathematical equations, and historic CG references.

In the early stages of production, maquettes of Homer and Bart were used as reference, digitized into the computer and refined to create convincing 3D versions of the characters. A whole new set of movements were needed to capture the spirit of Homer and Bart in 3D. This included the development of several small hand gestures and nervous ticks that convey Homer's signature nervousness - and Bart's mischievous nature - even when the virtual camera and characters are standing still.
