From the page: “Sculptor and painter Sako Kojima who lived like a hamster for nearly a week in the store window for her performance in oeWhy I Became a Hamster” in 2004, where she had to move all day long like a hamster, as well as running, biting wood, chewing toys and scratching wall. This went on for about 3 – 6 days.”
