yeah, if I get back to the boid flocking thing then looking into exanding that for routefinding/evacuation would be good. I've already collected some good url's on mathematical route finding processes which are often used in games.

On a side note I contacted the guys who make massive to ask them about their new lane based traffic system and they gave me some good ideas to look into fuzzy logic and how it could be applied. Constructing a 'brain' for each particle which then controls the relevant physics to move the 'body' and acting upon 'fuzzy' logic allows them an enormous amount of control as seen in their products.
