Blow Up Hall, Poznan, Poland

Blow Up Hall is a snazzy establishment described as an electronic art hotel; the design of the hotel is based around an intriguing video installation. The moment you step inside, you're a performer in the video being played in the lobby comprising 2,400 tiny images gathered from as many cameras inside the hotel. No keys or door numbers here, just iPhones. Every guest is supplied with an Apple phone which, through recognition tech, you use to gain access to your room. You can also use it to call your concierge, surf the net and view preloaded local tourist info. Text: Reuters
