The intersection of architecture and energy efficient lighting is on display in Lima, Peru where a collaboration between Phillips and the Peruvian bank, Banco del Crédito de Peru’s has created one of the world’s largest interactive LED displays. People passing by can touch a big screen in front of the bank’s building, and then lights on the building flicker, and sounds start to play and change depending on how the person interacts with the touch screen. The public art piece aims to engage city dwellers and hopes it will soften critical sentiments held by the Peruvian public regarding private banking.
