Luminous; Rainbow

Prismatica à Londres, R.-U.

A modern ice palace

This participatory installation comprises 50 pivoting prisms more than 2 metres tall. Each prism is made of panels covered by a dichronic membrane that reflects a rainbow of colours, which shift depending on the ambient lighting and the viewer’s perspective. The prisms are mounted on bases and fitted with projectors that give the installation a new dimension after nightfall. As the prisms rotate, chimes play music at different volumes.
