From the developer:
Produces stereoscopic graphs of mathematical functions. It also stereographs approximations to the 1st and 2nd order partial derivatives. Most people are able to view them without any paraphernalia. Stereographs are pairs of stereoscopic graphs that, when properly viewed, give a true three-dimensional effect.
