This will inevitably draw comparisons to Knuth's METAFONT and Computer Modern font family (as it should). It does suggest, to me, one particularly interesting use case: one could automatically measure parameters for an existing font, and generate similar-looking characters that might be missing from the font (e.g., small caps, Greek letters, Cyrillic, etc.). I programmed this once many years ago, using some ridiculously complicated PostScript and METAFONT programming, but I've since forgotten how that old code works.
I really wish people would add arrows to scrolling sites like this. Just a simple one at the bottom of the landing screen to indicate that you are meant to scroll. I had no idea what I was waiting for when I landed on that page and I started scrolling as it faded white so I assumed (maybe the title of this post?) it was a video.
