The Crown Fountain was designed by Spanish artist Jaume Plensa and inspired by the people of Chicago. The towers project video images from a broad social spectrum of Chicago citizens, a reference to the traditional use of gargoyles in fountains, where faces of mythological beings were sculpted with open mouths to allow water, a symbol of life, to flow out.

2) The Big Shadow project, Shibuya, Japan

The Big shadow project was created for the promotion of Blue Dragon, an X box game title. It focused on the primordial human experience of shadow-play. A person's shadow is projected as a giant shadow image, which can suddenly change into the shape of a dragon. This creates a new and engaging interactive experience.

5) Body Movies, by rafael lozano-hemmer

'BODY MOVIES transforms public space with 400 to 1,800 square metres of interactive projections. Thousands of photo portraits taken on the streets of the cities where the project is exhibited are shown using robotically controlled projectors. However, the portraits only appear inside the projected shadows of local passers-by, whose silhouettes measure between 2 to 25 metres high, depending on how far people were from the powerful light sources placed on the floor of the square. A custom-made computer vision tracking system triggers new portraits as old ones are revealed. With the assistance of 6 developers.'

Under scan by rafael lozano-hemmer

'UNDER SCAN is a large-scale public art project commissioned by the East Midlands Development Agency in England. Thousands of "video-portraits" taken in Derby, Leicester, Lincoln, Northampton and Nottingham will be projected onto the ground of the main squares and pedestrian thoroughfares of these cities. At first, the portraits will not be visible because the space will be flooded by white light coming from the world’s most powerful projector. As people walk around the area, their shadow will be cast on the floor, revealing the video-portraits. The short video sequences begin with the subjects in a still position turned away from the camera. As they appear within pedestrians' shadows, their bodies move and their heads turn to look straight at the pedestrian, potentially giving rise to an interesting range of interactions.'
