This is great timing — I've been putting off making animated diagrams for a blog post because the Manim setup was too much friction for what I needed.

Tried the live demo and the 3D orbit scene is surprisingly smooth. Curious about a couple things:

- How are you handling the animation interpolation? Manim's rate functions (smooth, there_and_back, etc.) have some quirks that are easy to get subtly wrong. Did you reimplement those from scratch or find a way to match the Python easing curves exactly? - For the py2ts converter — how far does it get on real-world scripts? I have a few older Manim CE scripts with custom VMobjects and I'm wondering if it handles subclassing or if it's more of a "simple scenes only" thing.

One suggestion: it'd be really useful to have an export-to-GIF or export-to-MP4 option directly in the browser (maybe via MediaRecorder API). A lot of the Manim use case is generating assets for slides/posts, not just live playback.
