What was that 65-foot-tall tower of printer paper boxes on the Cut? None other than Masters of Fine Arts student Bill Cravis' "Printing to the Sky," a pun on the sculpture "Walking to the Sky." (See, Walking to the Sky and Mao Yisheng to be Installed.) As part of Earth Week 2006, Cravis gained permission from the University to encase the Cut's flagpole in printer paper boxes for two days, April 17 and 18. Cravis collected the 400 printer boxes from clusters around Carnegie Mellon's campus over the course of the past year.
