The Cityscape project – (also called “How to blow 5 months of your life” by the maker)…
Approximately 7 feet past the window is a large single plane of wood with windows cut into it. The 7 x 11 foot plane of wood is actually two layers of wood with a ~1″ air gap where xmas lights are mounted to light up the inside. The front plane is thin (1/8″) and has the 1540 windows cut into it while the back plane of wood is 1/2″ sheets of plywood. The xmas lights (about 700 lights) are mounted behind the front plane so that the light bounces off of the plywood (back plane) to scatter the light so that pinpoints of light are not visible. The models of the Empire State and Chrysler buildings consist of multiple layers in order to simulate the effect of having lights shining on their own roofs.
Most of the display is painted in light grey latex paint for both weather-proofing and tinting of the light coming from the inside. However the front is painted dark grey to make it blend into the night sky above.
