Hi all,
I'm working on a space game with procedurally generated planets and thought others may benefit from the simplex noise functions I'm using.
This is ported the reference examples at:
http://staffwww.itn.liu.se/~stegu/simplexnoise/Noise.lua
The whitepaper can be found here:

Feel free to use. Be aware that perlin noise (predecessor to simplex noise) has a patent. Here's an alternative: OpenSimplexNoise
Enjoy!
Edit: That patent is for simplex noise
