by The United Nations has declared 2015 the International Year of Light, to showcase “to the citizens of the world the importance of light and optical technologies in their lives, for their futures, and for the development of society.”

Scroll down and let the trillions of photons stimulate your optic nerves to perceive colours and shapes and pithy factoids, and enjoy.
