The fish that live in this tank talk by using their body language. Designer Sangmin Bae created a device that explores the many aspects of biosonic and infrasonic sound. Video captured from a webcam mounted above the tank is combined with data from flow sensors inside the tank (measuring the currents created by the fish swimming). These inputs are combined to create audio and video output. Bae suggests that "even if the fish can't speak and express their feelings in a human way, it has energy and communicate in its own way". Here, vibration is the medium of interaction.
