Hi I have been working on a demo. Crowd control simulation
Demo and documentation found on my web site.

----------------
...
This crowd control simulation showcases intelligent locomotion for autonomous bots that are independent (have no prior knowledge) of their environment and requires no A* or time consuming pathing in advance. In whole, this is a control system that results in non-linear behavior and a more natural path creation. This document explains the different methods used in controlling the behavior of the bots as well as providing a user manual for the demo itself.
