I appreciate the posts that people are writing! But I don't like writing my own!! Anyway, I'll try.

I'm a research mathematician, interested in social media for both professional and recreational reasons. If you follow me, you'll see a mix of math and non-math.

Here are four pictures of things I've been involved in. I'll add a little more in a comment below.

Screenshot from the wikipedia page for the Hopf fibration, showing an image I made that is featured there. The image shows three layers of the Hopf fibration, corresponding to three bands on the base sphere. They are rainbow candy colored.
Screen shot from the wikipedia page for the associahedron, showing an image I made that is featured there. This image shows the front half, with vertices labeled by bracketings of the five letters a through e. Arrows for single re-associations connect the vertices.
Cover from the book 2-Dimensional Categories, by myself and Donald Yau. The cover shows three shapes like icecream cones, with blue, green, and yellow regions. Below are some 2-categorical diagrams with the same shape, labeled as they appear in the text.
Screen shot from pdf of the book Bimonoidal Categories... (etc) by myself and Donald Yau. The picture is a graphical representation of one of the axioms for bimonoidal structure, related to the interaction between distributive and commutative structures. There are 6 different arrangements of 12 boxes each, grouped or flipped in different ways, related to different applications of distributivity and commutativity.
