perlin noise preview

hi, here's something using the new perlin noise function, which will be available in the next revision... i just got too excited and could not resist the tempation to not post the example 
the entire terrain is based on this function. use the mouse position to scroll/move through the terrain. press the mouse and move left/right to scale it.

super-nice toxi!
Could you (or someone!) explain what the noise() method does?
I am guessing it is some sort of randomize method, but 3-dimensions?
A "for dummies" explenation would make me happy

cool & thanks guys! the best and most thorough explanation i know of is on hugo elias' site, which is one of the best comp.graphics sites in any way. so have a read there...
in brief, perlin noise is great for producing "natural" and smooth pseudo-random sequences. the 3rd dimension can also be considered time, so e.g. you can produce animated textures...
here's a replica of photoshop's "clouds" filter, only animated by moving through the noise space. use the mouse to steer...

UPDATE:::::::
just build in some little filtering to control the contrast of the clouds as also described on hugo's cloud site. the result is here:

That is very nice indeed! Both the landscape and the clouds are very cool. I think I should be playing with this cool function already
