I watched 3 Blue 1 Brown's video on colliding squares in an idealized frictionless environment reproducing an approximation of π in the number of collisions. I came up a little short in my understanding, but in my defense it is still 3.13 here ATM.

Tomorrow I will maybe do some CAD, and seeing as how proper design for the topological naming issue in CAD is due to π truncation in the tree, I'd call that my act of obeisance.
