viola (bill)

I went to see a Bill Viola's exhibition, my mother enjoyed it
I always have doubts about videos but....I was amazed by what I saw
of course I wasn't allowed to take this pic :)

This is:
The Sleepers
Seven metal barrels stand filled to the brim with water. A black-and-white video monitor lays submerged at the bottom of each one. The monitors show a video recording of a personís face while asleep, and a different person appears in each barrel. The room is silent. The light from the video screens emerges from each container and effuses the room with a soft blue glow.
