The unique beauty of the travertine exterior of the Getty Center is the result of complex geologic processes. Its intricate structure is derived from the rapid precipitation of calcium-carbonate from geothermally-heated hot springs. Calcification reveals the nanostructure of the walls of the Getty. An animated rendering of calcium-carbonate suggests a landscape as substantial as the quarries from which the travertine was cut. The animation was projected on the exterior stone walls of the museum as part of Jennifer Steinkamp‘s [re]vision project at the Getty Center in May 2011.
