A cube can be unfolded into six squares, and a tesseract unfolds to eight cubes.
Something—something like a Klein Bottle—or a tesseract—or maybe both of them together.
The hypercube or tesseract is described by moving the generating cube in the direction in which the fourth dimension extends.
Im also the Herr Reames of several other articles, such as on the mechanics of continua and the mass and inertia of the tesseract.
A four-dimensional hypercube, having sixteen corners. See more at hypercube.
