At time , the square of points at the bottom of the box represents the initial condition. At each time step, these points will diffuse by a random walk (Monte Carlo simulation) in three dimensions , , and . Each dimension can have a different diffusion coefficient, but in this Demonstration the three diffusion coefficients are assumed equal. You can also change the range of the initial square.
