Show HN: Wanim – Embed interactive 3Blue1Brown-style animations in your blog
Hi HN, I love 3Blue1Brown's animations and Manim, the Python animation engine behind them. So I wanted to run it in my blog to build interactive animations. But that wasn't easy. Running it with Pyodide is too heavy. I came up with a new approach: by patching rapydscript-ng (a tool that transpiles Python-like syntax to JS), I make it translate Manim code into JS, and pair it with a companion JS library. This lets it run the original code in a small enough bundle. Fortunately, after overcoming so

Adoption decision
Evaluate it against the tool or manual workflow it would replace. The stored record supports discovery; it does not yet establish reliability, lower operating cost or commercial adoption.
Unverified requirements
Not verified: license permissions, required hardware, installation steps, maintenance status and a representative task with its failure cases.
Next test
Choose one real task and a current alternative. Record the commit, environment, input, output, elapsed time and failure behavior; retain the result before recommending adoption.
