Letter M
Homework for 29.10 was to create a letter with Processing.
I used capital M, because it is a unit (em) in typography, just like point. My variables also derive from typographic line terms seen in the image below.

(how to embed images from other sites???)
You can download and tweak the sketch on OpenProcessing, but it is super slow, so you can also see it on my personal page, which runs on github.
(There is no way to embed it in the wiki, is there?)
