A Maze of Colour
The detail a low resolution image can show.
Figure 1.5 The maze is created by repeatedly choosing a starting position and
colour at random, and then reversing direction, again at random, avoiding any
obstacles. Great detail can be seen in this image, which consists of only 320 by
250 pixels. Some of the most detailed pictures shown in this topic are made up of
just over one million pixels. Often, though, only eight colours are used.
