Most people use paintbrushes and other drawing utensils to compose their art on canvases and paper. Cheeming Boey on the other hand, uses a Sharpie and depicts his art on Styrofoam cups. Ever since 2006, Boey started drawing on foam cups as a hobby and has now turned into a serious business. Each cup takes a few hours to several months to create and is sold for hundreds of dollars around the world.

Check out Boey’s entire collection of cup artwork on his Flickr page.
