Inspired by primitive life, Public Anemone is a robotic creature with an organic appearance and natural quality of movement. By day, Public Anemone is awake and interacts with the waterfall, pond, and other aspects of its surroundings. It interacts with the audience by orienting to their movements using a stereo machine vision system. But if you get too close, it recoils like a rattlesnake.
