Music producer Brian Eno is illuminating the iconic Sydney Opera House as part of a sound and light festival in the city. The Opera House' white "Sails" has been transformed into a canvas for a kaleidoscopic array of images. There is also a soundtrack to accompany the light show.
Eno said the constantly evolving display of colour, shape and form - already shown in the US and countries across Europe - would help people to "surrender to another kind of world".
The festival was launched with the first display of 77 Million Paintings, which will be shown from 1700 local time each night during the festival.
The Opera House's Luminous festival features music and performances from around the world.
