I recently went to a fun art exhibit on Van Gogh to review it for the magazine. It is called Van Gogh Alive, and is a multi-media art experience that was shipped over from Australia for a few months. There are no original Van Gogh pieces. Rather, the exhibit uses high-def projectors, surround sound and music to create an interactive experience inside a huge, dark room. It's the first time that something like this has com to Chile on such a large scale. It was fun! If there's one near you, I'd recommend it.
Here's my article, which has a lot more details: http://www.santiagomagazine.cl/exhibits/00941-van-gogh-comes-alive-chile
