Frabjous is a sculpture that consists of thirty identical parts which are assembled into a geometric star with twelve spiral vortices. A few years ago, a MAKE post showed how to make a cardboard version that requires many hours of hobby knife cutting. Should you prefer a cool-looking acrylic version, made from laser-cut components, there is now a kit sold by the Museum of Mathematics. It is a tricky puzzle to assemble, but when done, you’ll have a lovely, seven-inch diameter sculpture to enjoy.

Or if you want to spring for a fancy acrylic version with an iridescent coating that changes color as you move around, that is available, too.

    Any chance of getting a DXF for the pattern with the tabs on it, it would be fun to try and make some of these in different materials.
