Erwin Wurm’s eclectic practice—incorporating sculpture, performance, photography, video, and installation—is unified by a combination of formal concerns and a sense of humor. In a sculptural series featuring works including Big Gulp Lying (2010), Wurm depicts anonymous human figures entangled in sweaters and other clothing items, creating a silhouette that is both perplexing and grotesque. Wurm also encourages viewer participation in many of his works, such as in Confessional (2003), a sculpture resembling a dog house with head-size holes on either side into which viewers are encouraged to insert their heads.
