Thanks to Nelly Cheboi for bringing this formula, and all the accompanying links, to our attention.
In his humorous 2015 Numberphile video, Matt Parker discusses a remarkable formula by Jeff Tupper of the University of Toronto whose graph is the letters, numbers, and symbols in the formula itself. More precisely, this formula:
To find out how it’s done, check out Parker’s video, plus this background explanation and generalization by Shreevatsa R. You can use Tupper’s formula to plot your own name (or anything else you like) using this Python code provided by Kaito Einstein.
