This image was generated as an example for Ruby Quiz

This weeks quiz is about generating images from mathematical functions. Here is an example to see what I’m talking about.

depth: 3
red: Math.sin(Math::PI * Math.cos(Math::PI * y * x))
green: Math.sin(Math::PI * (Math.sin(Math::PI * y)) ** 3)
blue: (Math.cos(Math::PI * Math.cos(Math::PI * y))) ** 3
