# Animate Lean Proofs

This is a tool that accepts as input any Lean 4 theorem,

and produces as output a Blender animation showing

the steps of the proof smoothly evolving in sequence.

## setup

1. Install [Blender](https://www.blender.org/).

   I've been using v4.0.2, but any recentish version should work.

2. Install Pygments:

```shell

$ pip install pygments

```

## running

```shell

$ lake exe cache get

$ lake exe Animate Input/NNG.lean NNG.mul_pow > /tmp/mul_pow.json

$ blender --python animate_proof.py -- /tmp/mul_pow.json

```
