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.

Can you add as an end frame the overlay of all the paths? i.e. to bring back the faded tail and to show all the places where it has been? Nergaal (talk) 16:55, 16 January 2011 (UTC)[reply]
- DONE :) Purpy Pupple (talk) 20:30, 16 January 2011 (UTC)[reply]
Overall Support With same concerns as with Wikipedia:Featured picture candidates/BML Traffic Model, namely file size and if ogv will be supported by everyone. I like the pixel fading, nice way of keeping the motion visible. I think most people will get the general idea fairly quickly, so I think a shorter version, say about 30 seconds, would be better.--RDBury (talk) 15:20, 17 January 2011 (UTC)[reply]
- The filesize is much smaller than the videos in Wikipedia:Featured picture candidates/BML Traffic Model so I think it would be an even smaller problem. As for the length, the reader always has the choice to stop the video at any point he wants. I don't think there is any harm in having the full length video.

Support But you should shorten it to a minute or two. Nobody will sit and watch this for 11 minutes. JJ Harrison (talk) 00:01, 18 January 2011 (UTC)[reply]
Support, but I agree about the length. Cowtowner (talk) 00:12, 24 January 2011 (UTC)[reply]
