The concept behind Yukihiro Kaneuchi‘s Tiny Landscape in a Coffee Cup is simple — finish your coffee, receive art.

A bit more interesting than the average mug ring, this artsy coffee stain depicts a landscape. It uses the concept that as we grow and age, relationships are formed over time through interactions with others. Thus, as we interact with our coffee, a relationship over time is formed — with an empty mug. Does anyone else feel uncomfortable right now?
