I did a two-dimensional performance like the same situation where viewers watch its document video by letting them see it only in mirrors at a beauty salon.
If a performance has meaning to be appreciated on site or at a specified time, its document could be only a material which subsidiarily informs us the situation of site, or an individual medium which does not interfere the character of performance. Through this performance I tried to reduce the spatial, temporal gap of viewing between the actual performance and its document video to make a document which could maintain temporariness.
