About the Outside In sphere eversion

Click on the green arrow or the sphere on the right to go forward, the
red arrow or the left sphere to go back. The blue arrow cycles through
the amount of the sphere you see (all, half, onestrip, sixteenth).
(Version 2: the sphere pieces themselves no longer contain links,
just the arrows. Also,
the WebOOGL files now contain bicubic patches instead of explicit
polygon data, so the number of polygons drawn will change with the
interactively controllable patchmesh dicing level.) 3D Web version by
Stuart Levy and Tamara Munzner.
