That problem is solved by the subsecond crate (an offspring of the Dioxus UI framework), demo here: https://youtu.be/Kl90J5RmPxY?t=1288

It's not integrated in Nannou specifically, but they're showing off Bevy and ratatui in that demo, both very popular frameworks in the Rust world. (In fact, Nannou is in the process of being rebuilt on top of Bevy.)

Yes, I wanted to play with things like this, I love Rust, but nowadays I use things built in Python or Lua (like love2d) -- because I need fast interactivity for visual creative coding.

That is on the main branch. Behind the scenes [1] they're working a a huge rewrite to use the Bevy engine. A big effort that seems to be moving at a quite constant pace. It seems they're doing it quite rigourously: I've seen some issues in the bevy tracker where they check what is specific to their project, or where bevy can use some work.

yep looks heavily inspired by OF. Anyone knows whats up with that project? I was involved years ago, it seems to still be going but I think many people moved on?

AFAIK it's being rewritten to use bevy
