The Joy of Writing Shaders

Shaders provide programmers with a beautiful combination of art and math. Most other throwaway projects are devoid of any artistic value. In less than a dozen lines of code you can draw fractals. A few more and you can start creating intricate animations. The most interesting part is the unique perspective they force you into. Say you want to draw a circle in an imperative programming language. You need to break out a for loop and calculate the sin and cos of different angles until you have points all around the circumference of a circle.
