A method for kaleidoscopically painting an Icosahedron is illustrated by two clips. In each, an array of icosahedral simplex components is painted with an icosahedral Cyclon in rotation (cf. Palmer Bridges past). The Cylon used as a texture map is reproduced as the end frame of my movie. Colours have been modified. With 3,600 frames (0.1 degree rotation per frame) produces a smooth full rotation that will loop with no cusp. Images in each row of Clip 1 are aligned to the icosahedron's axes of symmetry: Edge, Face Vertex. They are the behind the scenes components of icosahedral symmetry simplexes. What I call: circumsphere, screens, altitudes, bases and hypoteni are surfaces produced by cutting along the planes of symmetry. Clip 2 shows a rotated close up of clip 1, the spherical icosahedra paired with their 'screens' counterpart. The corona virus's capsids have icosahedral symmetry.
