This is what happens when you make your movie black and white, add in some noise, throw in some rain, and put some ripple distortion on. It looks like an old movie, shot outdoors, and there's water all over the lens. Or looking out through a wet window onto a rain-soaked world. Or something. I'm sure you'll think of a way to use this kind of effect.
The possibilities for weird and wonderful visual styles from combining the different filters is huge. I can't wait to get these off Julian's desk and into a version I can play with, but it looks like that'll be quite a few weeks yet. Until then, I'll be as impatient as you!
Oh, wait, did we say rain? Yeah, there's rain too.
