Looking out of the windows of Seattle Children's hospital, patients eagerly search for new names painted on steel beams by union workers constructing a 7-story building across the street.

It all started a few weeks ago when one of the ironworkers painted a beam in tribute to a teenager who had died at the hospital, and whose father was a friend of the construction worker.

After that, other workers who knew of children being treated at the hospital painted those names on the beams: "Hi, Dede." "Hi, Zac." "Hey, Kyle."

And then, "it went viral."

Young patients who wanted their names on the beams put signs in their windows for the workmen to see, and checked back daily to see which names went up next, with the count now at some 50 names.
