Just picked up a copy of _Optics_ by Bruno Rossi (1957) and as I was flipping
through it, the graph(s) of the Cornescu spiral caught my eye.

Took me a bit to find an appropriate algorithm for the Fresnel Integrals to port
to SDL, and how to graph them.

I could probably spend a bit more time getting a better formula for the pigment
as a function of arc-length . . .

(C'mon Povvers - make and post more cool stuff!)
