Well.......why didn't I think of that?!

Pavl Duke Creates Insane Multi-Particle Video Player
"It's just video texture on the particles," ".... it's the default texture they pick up whatever [video] stream you've set." - Pavl Duke (quoted from Hamlet Au's New World Notes article, 6/2/2009)

Of course all the particles have the same video image, and you need to have control over the parcel media settings. However.....if you created several minimum-size plots (16sq meters) close together, you could place a particle rezzer in each with the video stream set differently for each plot. I expect one could create some stunning effects that way.
