Voices united light up York cathedral

Evoke

A specially commissioned project for Illuminating York 2007 in northern England, Evoke is a massive animated projection, that lights up the facade of York Minster, brought to life by members of the public, who use their own voices to "evoke" colourful light patterns that emerge at the building's foundations and soar up towards the sky. http://www.haque.co.uk/evoke.php
