Didn't know where to share this, but I thought maybe someone else finds this useful :)

I initially made this for an artist who does not have a builtin animation utility in their digital art program. They can export their frames/layers as usual and the program updates its preview automatically.

It is my first time working with async Rust on an actual project, which was a bit tricky but I think I like it. The preview timing is not extremely accurate but it's OK.
