As a lot of these replies mention - it's using interlacing to print frames using PNG.

Something I think is interesting here also, the server is holding each frame for two seconds before it sends that chunk to the browser, so the animation would look similar regardless of connection speed (2 seconds per frame + your browser's actually latency to the server)

It'd be nice to control the interval via a get parameter. Sure one could record and frame-by-frame it, but it'd be pretty easy on their side to have the uri default to something like `/interval/2/`. Maybe they thought of this, maybe it increases surface are...I think it'd be worthwhile for accessibility.
