Dust

So I sat with a friend who needs dust and speckles for his new project, but a certain kind of it. He didn't want the scanned-in dust I brought with me, it was way too much.
"Well, guess I could erase most of it ..." (him)
"Naa, that's too much work. Maybe I could do something with black cardboard and a bit of sugar, photographing ..." (me)
"Doesn't look like dust then."
"It's so simple, basically just a few random spots every now and then, it should be possible to program this in Processing, but I've never touched that. And we can't use any particle generator because it needs to show on single frames only."
"Particle generator? Like the one in Anime Studio?"
"Yes. And ... One moment. There's that thing called noisy interpolation, which is a script. So maybe I could write a script in AS ..."
"Can we test it?"
5 minutes later:
"So this layer contains one spot, and we set the interpolation to noisy ... woah!"
The spot was flickering here and there, and outside of the project as well. Just what we needed.
"Could we do this with some dust image? Like a hair?"
"Sure."
Open dust film, screenshot one speckle, import to AS, noisy interpolation on.
"OK, scaling to 1 or less, amplitude to 8.1 or so. You could also make a small movie with different dust shapes in it instead of just one image."
Finally he was happy with just 2 layers of random dust (1 speckle each). I've set the parameters a bit different on each layer, and because the scene was 1 minute long some numbers gave a too regular repeated pattern. No scripting needed.
