Here are some miscellaneous links and things that I've made.
In 2015 one of my students asked me about the relations between various mathematical structures. I got a bit carried away with my response, and the result was this graph.
I made this animation with Maple when I was still a graduate student. It was meant to demonstrate how the topological degree of a vortex is defined, but it ended up just being fun to look at. I still like it.
