Hyperbolic Paraboloid

This is a thickened hyperbolic paraboloid, described by

*z* = *x*^2 - *y*^2, -1.5 < *x* < 1.5, -1.5 < *y* < 1.5

The freestanding version clips the surface in the *z* direction slightly.


This model was designed as part of the [Manipulative Calculus](http://www.manipulativecalculus.com) project at Harvard University.
