This is a “triangulated” avatar of my favorite author Jorge Luis Borges. I use this style of avatar for myself on the internet. You can hover over this for a special effect.
I used Triangula —“an iterative algorithm to generate high quality triangulated and polygonal art from images” — to create this avatar.
To do this, I created a black and white source image with a transparent blackground. In Triangula, I used default settings and 256 points to generate the image above. Finally, I: (1) saved the result as a SVG (2) manually deleted background triangles, and (3) ran a Python srcipt to eliminate uneccesary attributes.
