Symmetry groups of real, bounded, three-dimensional objects are described
mathematically by the three-dimensional point groups. The beaded beads in this
collection are representations of the icosahedral group (top), the tetrahedral
group (middle), and the cube-octahedral group (bottom). Most of these beaded beads are hollow, held
open by tension. The objects were constructed with bead weaving, which is a
rapidly developing art form and provides a new medium that is rich for discovering
and displaying physical representations of these and other symmetry groups.
