A process or program that produces unpredictable numbers. In generative art it supplies the chance that makes each output different.
The rules are: take one of the existing pseudo-random number generators in the history of random number generation, choose colors at random and then gradually increase the number of pixels that you can perceive at the same time. If the random number generator was successful, it would produce a grayscale at the end of this entire experience.

Everybody else in the community of algorithmic artists was using standard random number generators. Therefore, mine possessed different qualities. A good random number generator would run continually for, perhaps, a month before it would start to repeat itself.
