The Hex Crystal is a twisty puzzle in the same vain as the Famous Rubik's Cube. Essentially, it is the three layer counterpart to the Rubik's Cheese(1-layer) and Rubik's UFO(2-Layer). The shape is something I have dubbed a Golden Elongated Hexagonal Dipyramid, the Golden coming from the fact that all the faces are Golden Triangles and Golden Rectangles.
Please note: Ordering direct from Shapeways will only give you a Do-It-Yourself kit in the color you chose, with assembly and finishing being left to the buyer.
