"The Greetings to the Sun" is an installation on the promenade of Zadar that during daytime stores solar energy to illuminate a huge (22 meters in diameter) round set of LED´s during the night. It accomplishes the "Sea Organ" that uses the waves of the sea to produce "natural harmonic sound". The combination of the two is a remarkable experience in the dark. The installation was also created by the architect Nikola Basic that created the Sea Organ in 2005.
