Go motion is a variation of stop motion animation, and was developed by Industrial Light & Magic for the film Dragonslayer.

Stop motion animation can create a disorienting staccato effect; go motion was designed to prevent this by moving the animated model slightly during the exposure of each film frame, producing a realistic motion blur. This frame-by-frame, split second motion is almost always created with the help of a computer, often through rods connected to a puppet or model which the computer manipulates to reproduce movements programmed in by puppeteers. Go motion was used in films such as E.T. and was originally planned to be used extensively for the dinosaurs in Jurassic Park, until Steven Spielberg decided to try out the swiftly developing techniques of computer-generated imagery instead.

Today, go motion is rarely used, if ever, as it is more complicated and expensive than computer generated effects, even for the novice filmmaker.
