In this lesson, M.C. Escher takes us on an adventure with two-dimensional creatures attempting to visualize three-dimensional objects. The creatures struggle to understand the concept of depth and must rely on their geometric intuition to understand the shapes crossing through their plane. Escher introduces a second method of explaining polyhedra by inflating them and projecting them onto the plane of the creatures. The lesson concludes with a discussion of the platonic solids and a challenge to visualize the fourth dimension.
