SlimShady: Procedural Shader Generator

In my silence over the past week, I've been experimenting a great deal with pixel shaders, hoping to get to a point where I feel that I can use procedural shaders to generate any type of texture - grass, rock, metal, etc. A procedural texture system will be critical in the development of a realistic virtual world.

To aid me in my search, I've created an innovative system (with the rather cheesy name "SlimShady") that writes, compiles, and executes procedural shaders. Not procedural in the sense that the shader generates procedural textures, rather, procedural in the sense that the shader is randomly generated by the program itself. Yes, SlimShady is a program that writes programs.

The real idea behind SlimShady is as follows: I can be working on something on my desktop and have SlimShady running on a laptop connected to my TV, such that the program will write a random shader, execute it and animate the seed value for a minute or so, then rinse and repeat. As I'm working, I can occassionaly glance at the TV to see if the shader catches my eye. If so, I hit return on a wireless keyboard, which instructs SlimShady to save a preview image and the full source code for whatever shader is currently executing. In essence, I can sift through an infinite number of shader permutations without having to touch the code! Not to mention, it makes a rediculously cool display...I could spend hours watching the program go to work on the TV.

Here are a few simple shaders written by an earlier version of SlimShady. The newer ones look even better! Also, note that the shaders are generally animated with a seed value - meaning they dynamically morph in real-time, making them far more interesting than can be conveyed in a static image.
