One shows the use of the Sort mode in cloner. Using this combined with effectors, you can switch between the object that is used to clone.
The next shows the Matrix object combined with Thinking Particles. By animating the Constrain parameter in the matrix object, you can control the clones by MoGraph or TP, plus blend between them. This scene also allows you to bake your thinking particles. Just bake the Matrix object. You can then disable the effectors and the Xpresso.
The final scene is a simple example of using the random effector, combined with falloff, to affect colour as well as PSR.
Hope they are useful.
