Forbidden Geometry
Forbidden Geometry by Christoph Spath in collaboration with physicist Paul J. Steinhardt. Quark Park, Princeton, New Jersey, 2006.
This sculpted form is based on three-dimensional models of four different shapes (zonohedra) that can be combined as building blocks to form quasicrystals.
This sculpture of a quasicrystal is made up of six building blocks, three fashioned from limestone and three from glass. The projections on the blocks represent the rules that define how the blocks can be combined to form larger structures.

Liberty Bell Slots
Plaque honoring invention of the Liberty Bell slot machine by Charles Fey. Market Street, San Francisco, California, 2010.
"Charles August Fey began inventing and manufacturing slot machines in 1894. Fey pioneered many innovations of coin operated gaming devices in his San Francisco workshop at 406 Market Street, including the original three-reel bell slot slot machine in 1898. The international popularity of the bell slot machines attests to Fey's ingenuity as an enterprising inventor whose basic design of the three reel slot machine continues to be used in mechanical gaming devices today."
