This shader takes a set of 1 pixel wide vertical slices from the source and interpolates between them to generate the output. The positions of (up to) 8 slices can be specified, along with noise and a y-position sampling offset to further distort the output.

The effect it produces is a horizontally-smeared, low-detail version of the input that can generate some nice abstract patterns.

It's based on the shader I made to generate the background scene for this project: Horizon | source

The 2 examples have the same controls, and show use with camera and a static image.
