credits music::lars leonhard - deep breath, crunch - grama & toe tac t.c. thanks sebl for shadertoys_05. his translation of the mandelbulb node let me research myself on shadertoy.com. I'm not the fittest programmer because I started late (in my adolescence computers were as big as living room cabinets and came from IBM). yes, code understood. it was more difficult to find parameters that are not iterated and to which audio can be added / multiplied without making them misshapen lumps. at first there were spastic twitches with every heavy drum beat. I could fix that. work continues
