At the Hayward Gallery in London, England is an art show all about light. Here is a link for it: http://www.king5.com/news/slideshows/Photos-Light-as-art-show-in-London-188846211.html?gallery=y&c=y&ref=%2F#/news/slideshows/Photos-Light-as-art-show-in-London-188846211.html?gallery=y&c=y&ref=%2F&img=0&c=y.
There is some really cool pictures on here. The one that really catches me is the first one with the rooms. Many other ones are pretty interesting as well, but that one is so simple, yet intense and interesting.
I would love to see this show – maybe it will travel over here.
