Prism is the technological show piece of the London Design
Festival. Located in a secret cupola, never before opened to the public, at the
Victoria & Albert Museum it is designed by digital artist Keiichi Matsuda.
It is a giant sculptural lantern hanging in the highest point of the museum.
Prism is made up of a series of faceted screens, on which
fast-moving streams of data about London are shot, changing every 15 minutes.
There are five projectors. All the information is gleaned from open data
sources and its intent is to portray the complexity of the city. Since there
are a number of different faceted sides to the structure, the images are
changing constantly.
