Long Lost Advent of Code Visualizations

As is tradition with Advent of Code, I make visualizations of some of the solutions. Nowadays, I do it in a fancy way using Apple’s APIs to draw, present, and encode the visualization for me.

Prior to that, I used to solve the problems with Ruby. I would output a series of images and then later encode them using FFmpeg to make my videos. How inefficient!

It also turns out, Google is yet again closing off a free service it got everyone hooked on. I’ve been reorganizing and re-uploading YouTube videos and found some of the old videos mentioned above.
