Everting the Sphere by David Ben-Zvi and Nathaniel Thurston

Nine stages in a sphere eversion, in William Thurston's style. We see 1/16th of the sphere (a 45-degree sector from pole to equator) as opaque, while the remainder is nearly transparent. A more detailed description appears in /u/gcg/pix/incoming/evert.note.

How to make it: "make" in data/sphere/evertseq. It depends on running the "sphere" program in /u/sphere/bin..
