TL;DR; I made a thing and plan on adding animations to it. Wanna help?
Inspired by the PPPPU Sisters/Girls/etc games, rhythmic porn animation viewers, I made a prototype, named Rythm Hearts in Godot.
It has Hearts (groups), each with its own name, link and Beats (named animations).
I invite anyone to contribute, with either groups of images or animations. Check the provided examples of Roxie Rockets (Hearts) in the Download section.
Here's some screenshots:
