[Algorithms] Trickly Water

[Zafar Q. <zaf...@co...>]

Hi,

I'm trying to create the effect of water spray landing on a camera with
a small lens size, thus making the drops rather large.
The bit I really need is how to generate animated normal maps that
resemble big blobs of water that warp and trickle to form new shapes.

Imagine I've drawn a few blobs of normal-map in Photoshop and put them
onto the screen as a post-process effect. I now need to warp and move
them.
Are there any utils that could generate this kind of thing?

Any ideas and suggestions at all would be most welcome.

Cheers
Zafar Qamar
