Does anyone know how to produce this?

I would really like to know how this can be implemented:
Does anyone know the math which is required to do this?

I think it's caledl magic (shaders).

I'm not quite sure it's the same, but it is very pretty.
Thanks for sharing!

I'm not sure about the first one. Initially it looked like a relatively simple color cycler but then more motion became apparent.
The second and third ones are a pretty simple "dilate" and "erode" image filter being animated over time and by an animated mask (in the second one.) LÖVE could do it with shader, or with a canvas or image pixel data, or maybe with a per-pixel mesh object.

You seem to be right in both cases! Dilate/Erode it is.
I just tested it with a picture of clouds and a picture of a cat in Gimp
Thank you very much! I had no idea what to look for.
Maybe I'll even find the first one by experimenting with Gimp
Edit:
Just found this video on
vimeo as well, with a more thorough description:
The video simulates the phenomenon of texture breathing, a distinctive and beautiful effect where colours and patterns appear to spontaneously dilate, contract and ripple. The effect is produced by computing the vector derivative of a source photo then applying iterative advection along the resulting axes. A secondary scalar field controls and strength and magnitude of advection and allows a range of interesting effects including pulsing, waving and breathing.
Hmm I guess I have to look some things up...
