Frabjous Special Edition

The special edition Frabjous is a sculpture and geometric assembly puzzle made from dichroic acrylic. The swirling geometric form is composed of thirty identical pieces that catch and reflect the light in stunning fashion.

Mathematically, the planes of the shape are the face planes of a "great rhombic triacontahedron," a self-intersecting polyhedron with thirty rhombic faces. But the puzzle piece is a carefully designed subset of the rhombus that doesn't intersect copies of itself.

Weaving the parts through each other so each remains planar is trickier than it looks. Instructions are included.

Recommended for ages 16+.

The word Frabjous is, of course, from Jabberwocky by Lewis Carroll, "O frabjous day! Callooh! Callay!"

Frabjous is designed by George Hart, Artist, Museum of Mathematics (MoMath)

Made in USA
