These are current and past projects. I get on kicks — something comes up that I want to investigate, learn about, understand, and then I end up wanting to share what I find — and here are some links! Get on my email list if you want to hear about new projects as they happen. (I’m currently working on some math finance material for people who have had some college math, more coloring ideas, and some coding and math art projects, but none of these are quite ready for general distribution.)
