Much has been made of Harlem's renaissance in New York City. Economic hardships from the 1960s to the 1990s led to its notoriety as a dangerous area, a high crime no-go zone. Few remember Harlem's golden period in the 1920s & 1930s, when it was a cultural Mecca, a haven for artists and musicians. Community leaders finally said "enough" in the 1990s and began reclaiming the once-storied neighbourhood block by block. Harlem Hospital has anchored the community since its founding in 1887. The hospital is currently in the midst of a $249M, 5-year renovation. A major feature of this renovation is a massive glass facade, comprising 429 panels that would measure 200ft long x 60ft high. High resolution digital photographs were taken of murals and were digitally processed by the GlassJet, a digital glass printer developed by Israel's Dip-Tech. This article explains how the project was successfully completed.
