Animation of a concave spherical magnifying mirror (makeup or shaving or bathroom mirror) whose curvature varies with time. The animation starts with the mirror flat (i.e. a normal plane bathroom mirror) and concavity increase to its maximum useful curvature (if the curvature is increased beyond this amount then the image becomes distorted). When the mirror is completely flat, the image is the same size as the object. As the concavity increases, so the mirror magnifies more. This capacity to magnify objects makes these concave spherical mirrors useful for detailed tasks such as shaving or applying makeup.
