Special Projects


An interactive artwork by Leonel Moura that broadcasts voices from the natural world in the face of the calamitous extinction of species caused by human action. The installation is composed of a set of 20 “cocoons” each filled with an electronic assemblage including a motion sensor, a micro-controller, a memory card, an RGB LED ring and a speaker. When a “cocoon” detects movement, it randomly reproduces a sound of an animal stored in a mp3 library and lights up the LED. The more people entering the room the more the environment will resemble a jungle disturbed by human presence.
