Para encorajar as pessoas a escolherem os serviços de Táxis de Frankfurt depois de terem bebido, em vez de pegarem no carro. O The Piss-Screen - um suporte colocado nos urinóis, que possibilitava controlar um jogo(neste caso um carro) que passava no ecrã à frente enquanto urinasse.
In order to try to encourage people to take a taxi with Frankfurt Taxi Services after they’ve had a few drinks, rather than get behind the wheel of their own car The Piss-Screen - a pressure-sensitive inlay set within urinals, enabling users to play while they pee was created. They installed this newfangled creation in male restrooms across Frankfurt, teaming up with a variety of bars, clubs and cafés. The game itself was displayed on a screen above each urinal, and would automatically start as soon as someone began to pee. The player could then control the car whilst relieving himself – if they wanted the car to go right, they simply peed to the right (and visa versa).
