Crazy Crescents is a mathematical art toy. Five colorful threaded crescent-shaped pieces are nested together inside a red ring, and inside each other. Each screw meshes with each of the other screws, as the screw angles is identical for all screws. The object of the toy is to screw it together, and make nice shapes.
