Guardian article about Saul Schleimer and Henry Segerman

On October 30th the work of Saul Schleimer and Henry Segerman was featured in an on-line article in the Guardian, written by Alex Bellos. The title of the article, "Pumpkin geometry", combines a seasonal reference, to Halloween, and a mathematical reference to the concept of stereographic projection. In a sequence of 3D prints Schleimer and Segerman show how to use stereographic projection, via light and shadow, to transform spherical geometry (the "pumpkin") into euclidean and hyperbolic geometry.
