Shortlisted as one of the entries for a competition in building a tourist attraction that will create a lasting legacy in the Olympic Park in London, The Cloud is a 400 fee-tall mesh tower. It is topped with solar powered plastic bubbles that are responsible for showing images and data like the weather information, the Olympic race results, and the number of spectators around. After the Cloud is built, it can also be used as an observation deck and a park. It has ramps, stairs, and lifts that carry tourists to the top and allow them to have a scenic view of the city below. With the use of the solar cells on the ground an in the plastic spheres, the Cloud has the ability to generate its own energy.
