I have tried a few different systems for audio visualization. The first I ever used was on a ZX Spectrum. I remember it to be uber cool. For what it was working with hardware wise it was a stunning achievement.

What I dont like in what I tried so far is the "Pick a template".

That goes boring really fast for me. I want it to evolve, to change, make it a journey instead of just repeating variations on a graphical "template"

I think AI (oh I hate using that term) bots could do a lot of cool stuff in this space.
