Abstract
A graphics system comprises an input device, and a computer for detecting changes in the position of the input device relative to a surface, and a monitor (63) for displaying patterns which follow the movement of the input device. The computer calculates at least one differential derivative with respect to time of the input device position and controls characteristics of the display patterns in dependance upon the or each calculated derivative.
