"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 teacup is treated in patterns, so that the untreated areas will pick up the pigmenting of whatever drink it holds. The color will grow and develop based upon your drinking habits.

I don't think it's for sale as of yet, but awesome idea! (via geekologie.com)

I saw these cups at her end of year show, they're available to buy now. I love the way these designs reveal themselves through use. Stain? What stain? Thanks to the more ways to waste time blog for reminding me. (via morewaystowastetime)

the more you use this mug, the more a hidden pattern reveals itself. after some time of use, its like you've got a new mug. clever indeed. (via supernaturale)
