Lee Harrison's ANIMAC system was originally called the Bone Generator. A body suit (harness) fitted with potentiometers gave the input definitions of a set of bones that made up the character's skeleton. From this set of 3D lines was produced on a 2D display the projection of the set of 3D lines via a set of analogue circuits.
