To continue exploring mathematical equations that create other wild, powerful, inspiring, provocative, sweet, curious, confusing, sometimes scary but always amazing three dimensional surfaces you can download our SURFER software. The raytracer you find at the Valentine’s Day special page is by Aaron Montag. It was created using CindyJS by Jürgen Richter-Gebert.
Did you know that February 14 is also “I love Free Software Day”?
Have fun!
