Noise is an unwanted random addition to a wanted signal [...] In Information Theory, however, noise is still considered to be information... (from wikipedia.org)

I would add, that sometime noise is the information. In these images an array/field of boxes is created, using the noise3, noise 4 and fractalNoise functions that MaxScript provides. The function is affecting each time the scale of the boxes.

Some experiments with fractals, using chaoscope and gaston. Both applications can generate fractal formations in 3d. However, the models are made out of (millions of) points, so I suppose that it would be impossible to export in any standard 3d format...
