Starting from the basketball script, which plots the the intersection of a sphere and a hyperbolic paraboloid, used Flow to
unwrap the curve, blend to two circles, and re-Flow to wrap around a sphere again, as described in previous post.

After a bit of work, here is a Genus2 Basketball.

In the re-Flow process, the circles became elliptical-ish. Should have used an ellipse, instead of a circle, for the blend.

Also added a final 45 degree twist.
