Asia's first and only sustainable light art festival, iLight Marina Bay is organised by the Urban Redevelopment Authority of Singapore, and celebrates the sights and sounds of Marina Bay, one of the focal points of Singapore's cityscape. The third edition of the festival was held March 7th through 30th in 2014, with the theme Light+HeART. As festival curator, the focus for the ONG&ONG team was to bring out the key message, that the awareness of sustainability through light is only possible if it resonates deep in our hearts - an enlightenment from within. This book will attempt to document the spirit and motivations behind the works made for the festival, through interviews with and personal essays by the artists, as well as those of our other collaborators. These will also include their thoughts about the lighting of urban spaces in general, bringing together their personal experiences and work as practitioners of the craft.
