The roof has historically focused on one primary function: keeping out the elements. New technologies, as present in Light-Emitting Roof Tiles, allow the integration of additional functions within roof surfaces. Manufactured by Lambert Kamps, the transparent roof tiles are integrated light-emitting diodes (LEDs) and designed to display text, pictures, and other graphical content in multiple colors. Information may also be animated, such as with an illuminated news trailer. Light-Emitting Roof Tiles also come with their own self-supporting solar-photovoltaic power system. via transmaterial
