Today I signed the steel beam for the Gates Center, the big, new, not-yet-shiny computer science building on the CMU campus (now called the "Gates-Hillman-Complex", after the Hillman Foundation donated additional funds).
It's a white painted steel beam that will be built into the building later. Very neat idea!
If you happen to be affiliated with CMU: The beam is available for all students, faculty and staff to sign on September 25-26 from 9 a.m. – 5 p.m. It is located behind Cyert Hall on Cyert Drive (access is available from Forbes Avenue).
