This came from old class mate Chris O’Shea aka Pixelsumo. He’s blogged an experiment some of his collegues at AllofUs (Orlando Mathias and Mickey Stretton) did with a tank of water and a projector.

“By projecting simple white geometric shapes on to the side of the tank, the light is carried through the volume of the water, creating the illusion of depth. Small dust particles in the water help capture the light.”

SPOTS, which is on show at Potsdamer Platz 10, is currently one of the world’s largest media facades. For a period of eighteen months, the eleven-storey glazed main facade of this office building will host the light and media art installation SPOTS.

The installation comprises a light matrix of some 1,800 ordinary fluorescent lamps that is integrated into the ventilated glass facade of the building at Potsdamer Platz 10. A central computer linked to a bus system can control all of the lamps individually, adjusting their brightness or switching them on and off. As a result, designs, graphics and animation sequences can be recreated on the facade as moving luminous images. The external shell of the building is transformed into a communicative membrane, which will be used primarily for displaying artistic material. With its large grid pattern and low resolution, the matrix of fluorescent tubes harmonises with the architectural scales of the building and of Potsdamer Platz as a whole. The aim is not to conceal the architecture with a media installation, but rather to implement its logical continuation.
