About this Product
The four dimensional analog of the cube; the tesseract is to the cube as the cube is to the square. Obviously it can't be created in our three dimensional world, so this is just a 3D 'analogy', if you like. Makes for a good curiosity to keep on your desk, just to look at when in thought or pondering a deep mathematical idea. And it's also the Designeract logo.
