Inspiration: Bret Victor
Victor is what I’d call an overachiever: at least from my perspective, he’s skilled, ambitious, productive, and visible all at the same time.
I remember seeing his web site for the first time as an example (exemplar) of hooking into the History API. Clicking on a link doesn’t clear the page and re-draw it; instead Victor animates the page transitions! Nowadays I take this sort of thing for granted, but Victor remains an inspiration.
