This talk is a live performance in mathematical illustration using Inkscape, a free and open-source vector graphics editor. I will draw topological concepts in real time, working through path editing, node manipulation, and frequent undo/redo operations. Rather than treating these as imperfections to hide, we will treat the whole process as a meditation on ctrl-z and ctrl-shift-z.
No prior experience with Inkscape is needed. Audience requests for SVG figures are welcome — let’s figure it out!
