Rebecca Horn

I can't find the installation i saw yesterday at Arco, but you can see some of her work with those pictures.

Rebecca Horn (24 March 1944, Michelstadt) is a German installation artist most famous for her body modifications such as Einhorn (Unicorn), a body-suit with a very large horn projecting vertically from the headpiece, and Pencil Mask, a mesh harness for the head with many pencils projecting out. In May-August, 2005 the Hayward Gallery in London held a Rebecca Horn retrospective.
