One quick learning from making this: it would be really useful to have CSS Mixins when using a lot of repetitive keyframes, as I do in this animation. The W3C seem to be quite against them, however.

Aside

I’ve updated my Speaking page to include more conferences, more videos, and a little on my speaking requirements and preferences.
