The material is dichroic acrylic, which changes colors as the angle of light shifts. This material is not frosted, so to avoid fingerprints in hard-to-reach places inside the sculpture, we include a pair of cotton gloves to wear during assembly.
The best way to see the colors is on video:
From the package:
Frabjous is a sculpture and geometric assembly puzzle. The swirling geometric form is composed of thirty identical pieces.
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!”
