The Visible Pinball Machine, a machine for playing pinball created by the Pacific Pinball Museum with transparent surfaces to show the normally concealed mechanisms. In pinball, players manipulate one or more steel balls on a playing field to score as many points as possible; a game ends after all the balls fall into the drain located at the bottom of the slanted playing field.Photograph: Kevin Tiell/Pacific Pinball Museum
