Interactive performing environment establish direct communication between human and artifitial object. Robotic entities are completely independent from each other and free from human control. Having their own distinct logic and physicality they react to specific local conditions in their own manner. The microprocessor inside of each entity receives information about its immediate environment from three ultrasonic sensors. Based on simple rules these perceptions are processed, specific "muscle response" is generated and transmitted to the servos. The robot moves in certain way while emitting light and sounds. One can observe the behavior of the robotic entities and try to find patterns in it. This way robots react not only to the environment but also each other and the people. The communication ultimately happens when a person (or a collective) gets involved in this unprecedented behavior without words and predefined conventions.
