Wall of Fire: Tetrahedron

Watch as the "Wall of Fire" in the National Museum of Mathematics shows the relationship between two and three-dimensional figures. This video focuses on the 2D cross sections that can be observed when a laser projects through a 3D tetrahedron. This video was submitted through the Innovation Math Challenge, a contest open to professional and nonprofessional producers.
