Mathematician/geometer Dugan Hammock of Quantum Gravity Research shows us a visualization of the 4-dimensional 600-Cell projected to 3D object (further projected, technically, to 2D on his computer screen.) The 600-Cell is a 4-dimensional shape made of 600 tetrahedra. When the Gosset polytope is projected from E8 to 4D at a certain angle, two 600-Cells are produced, the ratio of their sizes being the golden ratio.
