Digital Sign 8mm Before After Saint Simons Christian School needed a sign. They also needed an efficient way to communicate with their families. A Watchfire 8mm Digital Sign it was! The staff chose an 8mm pitch for clarity because it is placed so close to the families and visitors as they drive through the parking lot. We went to work to design a structure to match their beautiful stucco building with a terra cotta roof. How did we do? Oh… the monument (and roof) is made out of foam?
