A sheet of simplex noise

I made a new kind of noise texture function based on simplices. It runs faster. In higher dimensions like k=4 or k=5 it runs a heck of a lot faster.

To test it I created this "rubber sheet" surface. As the noise flows upward through the sheet, like a kind of magic wind pressure, the bumps on the sheet rise and fall with the noise value.
