Examples of patterns set up so that a short computation can be used to
determine the color of each cell from the numbers representing its
position. Most such patterns look to us quite simple, but the examples
shown here were specifically chosen to be ones that look more
complicated. In most of them fairly standard mathematical functions
are used, but in unusual combinations. In every picture both x
and y run from 1 to 127. d[n] stands
for IntegerDigits[n, 2, 7].
