These kaleidoscopes can be made to create any uniform polyhedron - that's why I call them polyscopes. The angles between the three mirrors determines which of three polyhedral symmetry groups is produced: tetrahedral, octahedral, or icosahedral. The way the bottom of the kaleidoscope is cut determines the specific shape that is produced. Laser-cut acrylic first-surface mirror makes up the body of the 'scopes. At the bottom a thin diffuser catches light from colored LEDs that is broken up and recombined by a 3d printed gobo.
