Come one, come all, you know youve got nothing better to do. Today there is a small outdoor exhibition in VIENNA, located next to the Rossauer Brücke by the canal (map below). Get up, get out, see some things, then walk some more. The first few dozen visitors can enjoy a free beer while they enjoy the free show. Exhibit open until it gets painted over.
Update from 2020: I had kept one of the beers as something to remember the exhibition, but a thirsty room mate eventually drank it after it had been expired for several years.
