In 1998, as restoration work was begun on the Washington Monument, Michael Graves was hired by the National Park Service to design scaffolding that would not obscure the monument.
Graves' design covered the aluminum framework with a translucent mesh, patterned to look like the monument's stones. The actual obelisk shone through even as it was being repaired.
Graves told CBS News' Bob Orr that the scaffolding celebrated architectural restoration itself.
"We think it's important, as a teaching device, to describe, especially to kids, that buildings need care," he said, "and so over a period of time, buildings deteriorate and they need to be cared for, just like we do."
