Abstract
Abstract A computer, such as a PC, includes a memory having an imaging program stored in it and a display unit, such as a raster scan CRT are all operatively connected together so that the computing unit can generate a signal that will result in an image being displayed on the display unit. The image includes a moveable figure that moves in response to inputs being provided via an input terminal, towards a set of targets. In response to the inputs from the input terminal, the computer initiates a set of actuators to move the figure wherein each actuator defines the movement in a given plane.
