Abstract
In their 1999 Bridges paper, “Polyhedral Sculpture with Hyperbolic Paraboloids,” Erik Demaine, Martin Demaine,
and Anna Lubiw discussed gluing together origami “hypars” to form structures they called “hyparhedra.” By
experimenting with this method, I discovered that using a rhombic triacontahedron instead of a dodecahedron as the
underlying polyhedron for the “hypar dodecahedron” results in a more symmetric model. The hypars are folded
from rhombic paper instead of squares, with the size of the rhombic paper determined by experimentation. Three of
the resulting structures, “Day,” “Night,” and “Pahoehoe,” were included in the Art Exhibits at the Bridges
Conferences in 2015 and 2016 and “Day” won the Best of Show People’s Choice Award in 2015.
