Description

Many modern machines work by breaking down images into small pieces or dots called 'pixels'. You can see pixels on television screens and computer monitors. This exhibit shows how an image, filmed through a video camera, can be changed by a computer. The pixels that make up the picture can be made to change colour and size giving different patterns and formations. Many special effects on television work by changing pixels in this way.
