I've always enjoyed making these demos after learning a new concept. For instance, I might apply Hooke's law to a fabric simulation. I find that in doing so, I am able apply the material I have learned in an interdisciplinary way, reinforcing my own learning.
Over time, I found myself collecting dozens of these demos. So, I created a Github Pages site to act as a sustainable hub for all of them. By making this site public, I can also easily share these demos and the insight I gained making them.
I like using these demos as a way to show people how math, physics, and code can all be combined to make cool things.
I'm working on documenting and adding each of these demos to my knowledge base.
