Brownian Motion / Random Walk

 Dear Netters:
 Are you aware of public domain/commercial programs for simulating Random
 Walk in 3 dimensions?  I am interested in the phenomenon of gel sieving
 and would like to simulate the same by using latex spheres.  We already
 have quite a bit of experimental data and would like to compare them
 with theoretical predictions.  I would prefer the code to run on SGI
 platforms with graphics capabilities (if possible).
