I’d like to share some “computer-generated art”. Below are images generated by a program that I wrote in 1997. It was written in Delphi 1 under Windows 3.1 on a 25MHz 386 PC (yes, one with a “turbo” button). The executable still runs just fine (but not much faster than it used to) under Win 7 on a modern PC.
The program is really simple, it just plots a discrete R^2 map (i.e. a sequence of points). The formulas are very simple too. Most of them are based upon the Gingerbreadman map http://en.wikipedia.org/wiki/Gingerbreadman_map (btw, “gingerbreadman” has tons of stupid anagrams)
