Brilliant Geometry

	An interactive exhibition on the art of mathematical projections was held Saturday, 13th May - Sunday, 4th June 2017 at the Summerhall Gallery : 1 Summerhall, Edinburgh EH9 1PL. School of Mathematics Colloquium "Brilliant Geometry" by Saul Schleimer and Henry Segerman, 3.00-4.30PM, Monday, 15th May, Lecture Theatre A, James Clerk Maxwell Building, King's Buildings, University of Edinburgh. Brilliant Geometry brings the creativity and precision of mathematics to the general public, using computer-aided design, recent innovations in 3D printing, and very, very bright lights! The exhibit includes a variety of hand-held projectors, shadow lanterns and zoetropes with striking geometric features. We invite you to play with the idea of dimension, of projections, of polygons and polytopes, and of tilings.
