30 identical pieces combine to form a beautiful sculpture
Finished size 6" x 6" x 6"
Designed by Mathematician George Hart
Made from laser cut, dichroic acrylic
Made in the USA
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!"

5 out of 5 stars
Not sure why this is listed as Level 10. It's not a puzzle, but a work of mathematical art. Putting it together is a bit of a challenge, but that's not the point. The iridescent special edition Frabjous is well worth the extra money. This thing is GORGEOUS (the photo doesn't do it justice). As your viewing angle changes, and even as the light changes, you'll see all the colors of the rainbow. It makes a great centerpiece, or you could even hang it as a sun-catcher. Highly recommended -- as art, but not as a puzzle
