I saw this article on Fark, a website I frequent that is usually a good source of current event news of all kinds. It's basically a site of links to other stories, and I swear I want to read two out of every three of the stories that are posted.
Anyway, some Belgian artist put a bunch of slides in the huge atrium at the Tate Modern in London. They look AWESOME.
I don't really care to get into the debate of whether they are art or not; I'm just saying they look and sound really fun.
