The Gen in Black puzzle was inspired by top-secret devices featured in the famous sci-fi movie of a similar name. This stainless steel take on the classic hedgehog in cage features two rotating sets of axial bearings which rotate independently, plus a slotted cover that prevents the hedgehog from escaping the cage (except when positioned correctly, of course). A high-design, precision update of a beloved classic, just as we've come to expect from Czech designer Radek Micopulos. Winner of Puzzle of the Year in 2012.
