This is a performance using wireless camera, Skype, body sensor, motor and arduino. The performance is collaborated with choreographers. There are three parts of the performance. First, audiences can experience an optical illusion through a gallery space miniature and Closed Circuit Television. People in the gallery can be seen as if they exist outside of the space through the camera in the miniature. Secondly, two dancers wear the camera, and their separate point of views will be projected on screen. Lastly, there is a network performance which is played in Seoul and Paris simultaneously through Skype. A dancer in Seoul plays musical instruments in Paris using the sensor on her body. In the same way, a dancer in Paris also makes sound for Seoul. According to environment and spaces, the project will be arranged flexibly.
