Perlin/simplex noise mirrored.

While I was working on another lighting effect, I added the ability to mirror the input layer instead of animating it. It gives the noise more depth and a pretty cool effect. I think I like it more than the original.

Have you ever tryed to calculate and show the noise in a 3d space? Like to render 8 noise fields with different z values?
