saatchi & saatchi have developed the piss-screen for the frankfurt taxi service to encourage drinkers to take a taxi home instead of driving drunk. it employs pressure-sensitive inlays in urinals which allow you to control a video game with your pee. they also designed the accompanying driving game in the vain of ‘need for speed’, a street based racing game with frequent crashes, to enforce the message of the dangers of drink driving. the piss screen has been placed in the mens restrooms of bars across frankfurt.
