This is part of the exhibition about Richard Rogers Architects, currently on at the Design Museum in London. It's basically an urban planning model, with buildings represented by clear block stacked on a large horizontal display. The display shows a series of different animated graphical data, such as building use, transport links, etc. and lights up the different "buildings" with different colours. The most impressive is the sun cycle, which shows the shadows cast by the buildings. It is by far the most popular exhibit - but the rest of the exhibition is pretty cool too!
