Particle simulation

Hi

I would like to a simulation similar to this one: http://www.youtube.com/watch?v=_OZv2kf_SCs

Can anyone point me to a tutorial or book that explains how to do it.

I've searched online with no succes. When trying to make a simple flow simulation i SW to test it out, I only get the option to use fluids and not solid particles like I'd like to.

Thanks in advance.
