In the week of the model makers fair, the Vienna underground passengers travelling on the U2 line - the line that travels to the trade fair - were witness to a unusual experiment: The Shrinking of Vienna.

With the help of the spoken diminutive, we re-recorded the classical station announcements. In German language it's possible to make a object sound smaller or cuter by adding either "-chen" or "-lein" to the word. So we managed to shrink the whole stretch of the U2 line in both directions.

The puzzle was finally revealed as the train reached the trade fair station.

Obviously some of the U2 guests spontaneously changed their plans: the previous visitor number record was increased by a further 4 % and the model makers fair enjoyed its best ever opening day.
