Basic Description
This is an 11-inch diameter sculpture made of laser-cut wood. It is assembled from thirty identical pieces. Each is an elongated S-shaped form, with two openings. It is similar geometrically to George W. Hart's piece Bouquet, but is a one-of-a-kind piece and is very different visually. The aspen is quite light in color but the laser-cut edges are a rich contrasting brown. The openings add nicely to the whirling effect. The appearance is very different as one moves around it. The name Frabjous comes from Lewis Carroll's poem Jabberwocky. "O frabjous day! Callooh! Callay!"A More Mathematical Explanation

"Frabjous" has 20 points, and is a rhombic triacontahedron. When fully fleshed out (when flat planes are created with each point as a vertex), it forms a dodecahedron. This information is useful in understanding how the sculpture was created.
To solve the puzzle created by the creation of said model, picture the dodecahedron in terms of a pentagram (now called the base pentagram) connected to five other pentagrams by sharing a line with each. Connect each vertex of the base pentagram to the tip of the opposite pentagram. Do this with every vertex in the dodecahedron. Unfortunately, all of the rods intersect at some point near the center. Adding two curves to the rod, one near each side, prevent the rods from colliding and gives an interesting star pattern when looked at from the correct angle. The two openings on either end of the S-piece appear to serve no purpose other than artistic pleasure.

About the Creator of this Image
George W. Hart graduated with a B.S. in Mathematics from MIT (1977), a M.A. in Linguistics from Indiana University (1979), and a Ph.D. in Electrical Engineering and Computer Science from MIT (1987). He has designed several geometrical pieces of art around the world, as well as helping with North America’s only Museum of Mathematics. He has worked at the MIT Lincoln Laboratory and MIT Energy Laboratory as a computer scientist, and taught at Columbia University for eight years and briefly at Hofstra Universtiy. After two years as a visiting scholar associated with the computational geometry group in the Department of Applied Mathematics and Statistics at Stony Brook, he was a research professor in the Department of Computer Science at Stony Brook (2001-2010). He is the author of over sixty scholarly articles and conference papers.
