One of the stranger symbols to ever cross the pages of a mathematician is the three-legged pi symbol, advocated by Bob Palais in his piece π is wrong as a symbol for 2π (and as opposed to using the Greek letter tau for that purpose).
Some examples of three-legged pi in action:
Is there a standard (La)TeX way to get this symbol? I had a look on google, detexify, ctan and symbols-a4, and didn't get anywhere.
(Also: I don't particularly intend to use it, and definitely not in a publication. But it'd be nice to have around.)
