This month one of the most unusual hotels in the world opened in Poland. Blow Up Hall 50 50 is a luxury hotel in Poznan, Poland, which is themed around electronic art. It is built around an interactive art project by Rafael Lozano-Hemmer, which consists of 2,400 scrambled images of hotel guests doing whatever they’re doing. The hotel has 22 bedrooms and instead of being given a key for your room, you are instead given an iPhone to locate your room (especially handy as none of the rooms have numbers). The action of reserving a room is also unconventional. When you make your reservation you are presented with three colours, three pictures and three numbers. The choices you make, dictate what spirit animal you are and you then booked a room accordingly. Sounds like amazing fun!
