Richard began using Apophysis 7X on May 19, 2013 to generate images algorithmically. On September 21, 2013, Chaotica was added to the software toolkit to take advantage of its excellent rendering engine. Richard concluded his fractal imagery experiment in December 2013.
This deviantART profile picture and the corresponding avatar were created algorithmically. If you would like to see the equation that produced the picture it is available at Wolfram|Alpha. Simply click on the link and wait a few seconds for the image to appear and then a few more seconds for the equation to be displayed.
