Winner of the the 2012 Good Design Award. The Or2 project, designed by Orproject, is a single surface roof structure that reacts to sunlight. When in the shade the segments of Or2 are translucent white. However when hit by sunlight they become coloured, flooding the space below with different hues of light. At night Or2 transforms into an enormous chandelier, disseminating light which has been stored by the intelligent photovoltaic cells.
