Original - Two dimensional random walk for one particle on a 400 by 400 lattice. One million steps shown at 1500 steps per second: at each step, the particle randomly moves to any position in its Moore neighbourhood. The lattice has toroidal boundary conditions (i.e. going off one edge reappears on the opposite edge). The path traced by the particle slowly fades out. In the scaling limit, random walk approaches the Wiener process according to Donsker's theorem.
Reason
This is, in my opinion, the best media on Wikipedia demonstrating 2D random walk and its similarity to Brownian motion. Moreover, it is highly intriguing to look at.
