Dutch designer Rolf (no last name, apparently) created a series of cool cross-sections of "teapots and kitschy vases" by embedding them in cement blocks and then sawing them in half: "By cutting the same type of teapot in half, in two different ways, two totally different shapes emerge that are both very characteristic and to a certain, but different degree, recognizable for the shape of a classic teapot."
