 > Stain is a set of a teacups designed to improve through use.
 > This project examines the assumption that use is damaging to a product
 > (For example, scratches on an iPod).
 > The interior surface of the cup is treated
 > so as to stain more in predetermined places.
 > The more the cups are used, the more the pattern is revealed.
 > Over time they will build up an individual pattern dependent
 > on the users personal way of drinking tea.
