I've manage to compile it and it gives a result. However it doesn't look 
really like the noise.

 From what I understand it uses a permutation texture and a lookup 
texture but they don't provide it. I think I can figure it out from the 
array of pseudo-random number in the C code. For now I'll concentrate to 
better understand GLSL altogether but I'm pretty confident it'll work.
