Flocking animation in povray update

Flock05h
Uploaded by pterandon

Here's an animation hosted at dailymotion.com. I am attempting an AI system where particles are able to avoid collisions with each other, avoid collisions with objects, and track after a "goal particle". The particles appear to meet these goals well, except for the fact that they look like they are bouncing off of the grid. I was hoping for a view more like that of a flock of seagulls gracefully and smoothly negotiating their way through the maze. This looks more like monkeys driving bumper cars. I had been pleased at how well this sysem had come together, but it looks like I would have a lot more work to do before I could get my "flock of seagulls" look and feel.
