Uses mirrors at varying angles and colored geometric reflections to illustrate principles of symmetry operations. Illustrates that mirror angles of pi over 2, pi over 3, and pi over 4 produce dihedral groups of order 4, 6, and 8 respectively and points out rotational subgroups. Shows how, if three mirrors with dihedral angles of pi over 3 are set perpendicular to a plane, a true kaleidoscope is formed by each pair of angles. Concludes with a series of colored illustrations of tessellation.
