* I may have gotten a little bit sidetracked from my original goal of a 'boids' simulation... but I think this turned out cooler than any boids I could've fit in a #tweetcart otherwise!

* Boids are a way of simulating flocking birds using simple rules. The wikipedia page explains it well: [https://en.wikipedia.org/wiki/Boids](https://en.wikipedia.org/wiki/Boids)
(I like to think that they were originally just birds but the author had a heavy accent)
