Diffusion Limited Aggregation Applet

Yes, I wrote an applet. I know it is very 1990s but, amazingly, it still does the job quite well. Ok, next time I should really use Flash to do this.

The Applet simulates Diffusion Limited Aggregation as described in Chaos And Fractals from Peitgen, Juergens, and Saupe. It represents ions randomly wandering around (in a Brownian motion) until they are caught by an attractive force in electrochemical deposition experiment. This kind of phenomenon occurs at all scales, for example it happens in the distribution of galaxies. You can play around with the applet at
