Presenting, Balanghai, by Leo Gerardo Leonardo, another one from the BGC art installation series (There are apparently 7 of them, not 5 as I'd originally said. Whoops! Five down, 2 more to go!). The Balanghai is a kinetic sculpture that moves with the wind and was inspired by balanghay, the name of the boat that carried the first Malays to the island. The sails represent the three major islands in the Philippines: Luzon (where Manila is), Visayas and Mindanao.
