Nice effect, Michael. How was C4D used?

Thanks, Dennis. Essentially I took two planes, one directly in front of the other, and mapped still images onto both. I used a noise function to control the transparency of the nearest (to the camera) plane. Both planes are rotating and scaling at different rates, directions, etc. Finally, I placed a refractive sphere between the camera and the planes (whose surface is being modulated by a moving bump map). The last step was doing a couple of SA texture passes, and then using another noise function to control the blend between them. I was experimenting w. ultra contemplative music, so this version moves quite slowly. I'll post another version at some point soon that is closer to the original speed, and which perhaps gives a better sense of the process.

Amazing coincidence. I've been working on some sketches in C4 D that use two planes, one in front of the other, each mapped with a different SA image, but I'm using the alpha channel with a plugin called Enhance (biomekk - great stuff) to control the transparency. I used Enhance for all the displacement mapping in White Noise - not sure if you ever saw that but it is up at my site.
Anyway, great minds... ;-)
I've also had good luck using a transparent plane smack in front of the camera with an animated bump map... nice effect, and one that sort of duplicates an effect I used in POVray, where I could actually map a movie onto the camera lens... soft of like an animated cracked camera lens filter.
Anyway, in your sketch, is the camera looking at the refractive ball? and you have the noise function in the transparency channel, right?

That is an amazing coincidence! Thanks for the Enhance tip, looks very cool. I love your piece "White Noise!"
Yes, the camera is looking right at the refractive ball, and yes, there is noise in the transparency channel of the two planes, but there is also noise in the bump map of the sphere's surface....

"Do you want a paint preset? Or do you want to use interactive warp? There are some options in there that use an adjustable local sphere radius for the interactive warp effect."

Kai's supergoo..

John, a long time ago, years in fact, I asked if there was a preset that imitated the old 90s program 'Kai's supergoo". You put a really cool preset up which did just that, I've trawled my laptop and backup and cannot find it...any chance you or anyone could put it up again?thanksSee More
