In this interactive exhibition, see how and why cities are changing and what urban communities around the world are doing to improve city life. Look at what data has to tell us about the urbanisation of our planet in a dramatic visualisation. Get hands-on to explore challenges facing cities around the world, from the use of digital technologies to housing and homelessness. Discover new innovations from social housing in Chile to underground bike storage in Tokyo. Share your opinions and find out about local London initiatives too.
