Basic screen savers. Bootstrapped by https://github.com/sdbondi/go-glfw3-play/blob/master/main.go

TODO

• Figure out

• Suggestions from Gerald btw, for super fast speeds, look at making a fragment shader.. you only need to render one box, and have that shader draw on that box as a texture there's also shadertoy which is an online shader experimentation thing that runs in WebGL

Algorithm

• 1 - Pixel colour depends on distance from a point (0.0)
• 2 - Pixel colour is the average of the 3 pixels on the row below + the previous colour of the pixel. See rule 2 at https://www.youtube.com/watch?v=NSI4KKjYS_w

How do I get set up?

• brew install --build-bottle --static glfw3
• brew install glew
• go get
