This is a rough playground for making animated GIFs with vector drawing functions from Vecto/Vectometry.
To try it:
$ (cd ~/quicklisp/local-projects && git clone https://github.com/xach/octree.git)
> (ql:quickload "octree")
> (in-package :octree)
> (test-hex-overlap-animation "whee.gif")
whee.gif will look something like https://twitter.com/xach/status/1336489161411407877
See text-art.lisp for some other fun text-oriented animation. Needs a TrueType .ttf font file to work.
