Thank you. :-D

Yep, that's the one. Start a particle from each pixel, colour that pixel 
according to where the particle is now. (Using any arbitrary colouring 
algorithm you fancy.) You *could* use an image map, for example...

Clearly I'll have to put the result on YouTube at some point. ;-)

Yeah, possibly. Or maybe add some white or something. Of course, when 
it's in motion, you can tell by how quickly each point changes colour.
