Interactive Demos

Why this?

This page contains a collection of the interactive demonstrations written as playable Marimo notebooks, which we’ve been using in our lecture notes as well as assignments. This page serves as a compilation of all the interactive examples. You DO NOT need to have a server in order to run these demos, as they are written in WebAssembly and accessible in your browser.

Many of the examples showcase how the equations in our class can be transformed in to simple simulations. Click a tile below to interact with them!
