Note: The category for this curve is correct; it is (or at least appears to be) a nephroid rather than a cardioid. The nephroid is formed when the cup is in the shape of a cylinder as appears to be the case in this photo (see [1]). It appears that caustics in the form of a cardioid are possible as in File:Caustique.jpg, but with certain conditions on the angle of the light and the shape of the cup.
