How to make psychedelic backgrounds for a greenscreen live performance?

Hello everyone!

I am getting ready to make a video for my friend's band. His idea is to try to emulate the feel of some of those 70's videos with the band in front of a green screen(at the time, it was probably blue) and a bunch of psychedelic visuals. Here's a couple examples:

Black Sabbath -





Frumpy -





I feel confident in my multicam editing and greenscreen process.. Lighting, placement etc. My problem is with the psychedelic graphics. I can see that Black Sabbath used a lot of still pictures, that I guess they zoomed around and color-cycled through.. Any pointers on that color-cycling technique?

Also, I would REALLY like to pull off the style like in the background of the Frumpy video above, where it will show one band member mirrored a bunch of times, kinda blending together with crazy colors. This would be awesome to be able to pull off.

Any help totally appreciated, and thanks in advance!

Thanks a lot! Knowing the name of this effect was what I needed. Time to make some feedback!

Cheers,

What differentiates that plugin from the built-in Effects>Generate>Cell Pattern?
