ESI Design created a special display based on 1584 polycarbonate LCD panels with a low resolution grid of LEDs behind the panels to represent all 32 levels of The Tower at PNC Plaza in Pittsburgh, USA. The patterns shown on the display reflect the green and environmental control systems in the building. The aim is to reflect the green design philosophy of the building to visitors and passers-by. There is a website to explain the display and we have put a video below.
