Details: This is a beautiful collection of polyhedra that you can build if you have enough hinges. That is a mighty big if, but these do look great - good enough to justify buying the parts specifically through Bricklink or LEGO's online Pick a Brick to give it a shot (well, for the geometry teachers out there, anyways). The technique's not too complicated, but the execution is perfect.
