London has a brand new visitor attraction, which is claimed to be the world's largest exhibition dedicated to the future of cities. The Crystal users interactive exhibits to discuss subjects affecting cities; such as climate change, population growth and increasing urbanisation.

The brief for Event, which was responsible for creative direction, design, content interpretation development and delivery, was to make it real and sensational. Siemens supplied the technological material and research.

The main area of the exhibition is divided up into zones, which is anchored by an "attractor" which represents a real urban sustainability challenge; for example, a full height fire has been created using steam, lighting and projections. Solutions are then presented which encourage visitor participation.

All visitors have RFID cards used throughout the space to enable them to tag themselves into interactive tables. At the end they can unpack their journey to see all the solutions with which they have engaged.

Topics such as transport, urban planning, energy supplies, terrorism, water and health are all discussed. An insight is given into the years 2030-2050 if all the sustainability solutions are embraced.
