pnoise is a pure-Python, Numpy-based, vectorized port of Processing's noise() function. The p in pnoise stands for Processing, Perlin, Python, "port", and probably other things I haven't though of yet.
I wrote this port before switching to vnoise and, although I'm no longer using it, I figured I would keep it around.
