If you need another excuse to visit Croatia, (really?) this is it. The Sun Salutation, located in Zadar, is a public pavilion that is comprised of photovoltaic cells inset with LED's that burst into light when the sun sets. The site is also home to the Sea Organ - a musical instrument that is powered by the rhythm of the ocean waves to create a calming seaside melody.
Definitely on our 'must-see' list!
