Brownian motion is “the irregular motion of small particles suspended in a liquid or a gas, caused by the bombardment of the particles by molecules of the medium: first observed by Robert Brown in 1827.” (dictionary.com). This is a simple MaxScript that uses particles in order to simulate Brownian motion. The script has to be placed in a script operator in the PFlow view in order to work.
