Hi, here's a composite node breakdown of the recent particle test I did wit Blender 2.53. The .blend file will be available in the article that it is written on. I'll update you through posts once it's available.
Been very excited with Blender's boids lately. This is just a test animation which is a result from my upcoming Introduction to Blender's Particle System (Part 2). I have included in the article my setup which would also include my compositing steps.
