Symmetric things are often more attractive. Symmetry is also a geometric idea: things may have reflection symmetry or rotational symmetry, and so on. What better way to end this series of Geometry lectures on design than by showing how the design of interactive devices, like mobile phones, relates back to symmetry? Symmetry makes a versatile link between human perception and what interactive devices should be designed to do; it makes a constructive link between what is attractive and natural and what is easy to use.
