Dynamic Paint particle growth
For this animation I used a dynamic paint canvas on a plane that emits hair particles based on a wet map. I used another particle system as the dynamic paint brush

blender particle experiments - wobble
in this part of my blender particle experiment I made an object that wobbles on particle impact. I used dynamic paint in wave mode to generate the wobbles.
At first I planned to use a soft-body simulation, but using the dynamic paint waves turned out to be a lot easier and more stable

blender particle experiments - dynamic paint pseudo-reactor particles
For this part of my blender particle experiments I used dynamic paint to generate an effect similar to the reactor particles from blender 2.49
I used 2 particle systems, the first one is setup as a brush for dynamic-paint, and influences a vertex-group on a plane.
The second one is a hair-particle system that uses the vertex-group for length and density of the created particles.
so I can create a bunch of smaller particles where the big ones hit the plane.
