Stereographic projection is a mapping from the sphere to the plane. Imagine straight lines going from the north pole of the sphere down onto the plane. Each line hits the sphere at one point and the plane at one point. Stereographic projection maps that point on the sphere to the point on the plane.
If a light source is positioned at the north pole of this sculpture, the rays of light effectively perform stereographic projection! The curves on the sphere cast shadows, mapping them to a grid of straight lines on the plane.
