Sky walker: Edan McPherson of the LaPaloma Fire Arts Studio in California reinstalls a figure to the “Walking to the Sky” art piece Wednesday at Carnegie Mellon University in Oakland. Several figures had been removed for routine maintenance by McPherson's studio. The sculpture is the work of CMU alumn Jonathan Borofsky.
