Mille Brown is the Jackson Pollock of acid reflux. She's a performance artist who drinks colored milk, then vomits it, then sells whatever she vomits onto. Brown started vomiting rainbows in 2007, allowing herself to dribble colorful upchuck down the front of her shirts, then selling the shirts; she has since progressed to vomiting onto white canvases, which provide "more longevity" and "room to experiment with pattern and color." The above video depicts a 2010 performance for Nick Knight's ShowSTUDIO.com. The website lists the resulting canvas, "Nexus Vomitus," for sale at £1500, or $2400. [ShowSTUDIO via Buzzfeed]

Update: Intrepid commenter Back in Nom Nom Nom notes artistic synergy with Keith Boadwee, an artist known for (NSFW link) squirting paint out of his anus. Art about art: a brave future of putrid body functions beckons.
