The performance “Duality” is part of the “Symptoms of the Existence Cycle”, which is a cycle of 12 exhibitions, done during one year. Each of them was started with a performance, which is connected with the exhibited works. The works of art got modified and a new shape every month. At the same time, with these performances, I explored the question of who is actually the observer and who is the observed. I wore a smiling mask, in order to bloc with the verbal communication of the spectators, as well as to raise the question of who is behind the mask. Plenty of different emotions could be seen during these performances. Actually art is a mirror reflecting ourselves – and at the same time it is a way to our “real self”!
