10 pics of the new geometric light sculptures in Hayes Valley

A dodecahedron and a rhombicosidodecahedron make their stunning SF debut

Patricia's Green, the unofficial town square in Hayes Valley on Octavia, has been a boon for unique art pieces over the years. The Temple, created by artist David Best, is the area’s most noted example. Now a new temporary installation has come to the neighborhood: Dodi and Trillian, two steel sculptures created by Yelena Filipchuk and Serge Beaulieu of the artist duo, HYBYCOZO.

Dodi, a six-foot-tall dodecahedron (i.e., a 12-sided shape) consisting of repeating pentagons, and Trillian, a 10-foot-tall rhombicosidodecahedron, boasts a total of 62 triangular, square, and pentagonal faces.

While the two pieces were inspired by Sir Roger Penrose’s mathematical formula based on a field of geometry known as tessellation—"a flat surface is the tiling of a plane using one or more geometric shapes, called tiles, with no overlaps and no gaps"—they also resemble the doily lace patterns found on your grandmother’s holiday cookie plate.

What’s more, they’re both lit from the inside, making them equally exciting to behold come nightfall.

As Hoodline reports: "The sculptures were originally intended to be large enough to allow visitors to stand inside, but due to safety issues and concerns about homeless campers, the city asked HYBYCOZO to close them up."

Visitors can look at them via a peephole or admire the shadows they cast from the inside out.

"We are thrilled to present these incredible light sculptures by HYBCOZO in Patricia’s Green," said Director of Cultural Affairs Tom DeCaigny, in a written statement. "The artists have taken a complex mathematical concept and made it accessible through art. They are a wonderful temporary addition to the neighborhood that can be experienced day and night."

The pieces will be on view until November 2017.

A lot more things we want to bypass tonight; but for a bit, this'll do.
