Make a layer out of particles

I have a video footage layer and i would like to make it come together through flowing particles, as a cool transition. Then i would like for it to be blown away like sand. Does anyone have any tips or good tutorials on how to do this? I would really like to use Particular, but any particle system will work.

I'd imagine you'd have to set the video footage as a layer map for the color of the particles and set it to RGB to RGB or RGBA to RGBA. Then you'd have to keyframe the displacement or flow values for the fractal noise to whatever you like.
also, there used to be a project available to show you how to make text disperse and fade out, but it's not on the site anymore. It's called texttosand.aep if you want to look around for it. Someone here posted a link to it in another thread about a month or so ago. I downloaded it at the time, and have it somewhere.
I messed around with that project file and figured out how to get the text to coalesce from particles into words. Basically I removed one of the ramps for opacity (i think) and reversed the direction of the dispersion layer (i think... maybe vice versa), then put that into a comp and time reversed the layer so that the particles would work in reverse. I tried a bunch of different techniques to control the particles, but this is what eventually worked.
