What does the average of all fonts (on one person’s computer) look like?
It turns out that overlaying letters from different fonts on each other doesn’t work too well – you get blurry results, like composite faces. But if you just take evenly-spaced points along the boundary of each letter in each font, and average them together, you get something quite readable.
I’m reminded of Metafont, which is used by TeX to specify fonts; each font is specified by a bunch of parameters, so averaging fonts becomes averaging numbers. There are some nice illustrations of this in the chapter on Metafont in Douglas Hofstadter’s book Metamagical Themas.
