The technology exists, why not make the Arch into the largest hologram projector in the world?
What if 3-D images were displayed between the legs of the Arch? What short of shows could be put on? News, weather, sports games, and films could be displayed on a 630-foot screen that looks different from all angles! With hologram technology already a reality, we could see this wonderful monument transformed into a truly functional art piece. We could have our own hologram of a ball dropping on New Year's eve, bigger and better than New York's!
