500,000is a big number. But did you ever think it would make a rug? Using 500,000cigarettes, Xu Bing created a tiger rug using the orange and white sides of the cigarettes. The smell of the tobacco is so strong, you get a whiff of it all the way down stairs. Laying 40x15ft, the massive tiger lays on the hardwood floors of Mass MoCA. Even though the trip might be long, this, and the rest of the museum is worth seeing.
