From the jungles of Singapore to the coral reefs of Indonesia, from the ornaments of Australian budgies to the deceptive traps of carnivorous plants, this film explores a world where light becomes language. Seduction, camouflage, overexploitation, reproduction: fluorescence directs behavior, often without us noticing. A light phenomenon that science is just beginning to decipher.
