This demo has been implemented by Thorsten Beier and is powered by:

• emscripten-forge which provides the wasm compiled packages
• pyjs which implements the python wasm runtime and the python-javascript FII
• The pyb2d-package which implements a python interface to Box2D
• The Box2D C++ 2D rigid body physics simulator library
