A simple star field effect that doesn't glitch around when moving the object. With higher resolution there is twinkling

This is a test to see if UV filter-type shaders can be combined with regular shaders http://shaderfrog.com/app/view/42 . This was written by hand but is an exploration of possibly creating "filter" types for ShaderFrog, where one shader could potentially become an input to another's texture2D method.

This is a simple pixellation effect by flooring the uv coordinates to only sample from a grid. Note this image has artifacts because ShaderFrog currently uses mipmaps on the image.

Takes an image and adds ripples to it. Hopefully one day the texture2D will be able to sample another shader!

This is a variation of the fireball effect http://shaderfrog.com/app/view/30 that uses the same noise functions, but none of the color functions.

Another way to do a checkerboard. Doesn't apply as well to a sphere. Check out http://shaderfrog.com/app/view/4 for the other variation.
