On the screen, one sees the authors of this work dressed in the uniform of ordinary clerks. Before the intervention of the viewer (before communication with him/her) they stand still, shifting slightly from one foot to another and looking straight at the audience. However, as soon as someone takes the advantage of the drifts, the bodies of the artists (or their virtual counterparts) begin to undergo the incredible mutations. They transform beyond recognition, literally losing the human form. Artists donate their bodies for a "commutative" experiment (hence the author's wordplay). As it usually happens with an interactive art object, the audience becomes an essential participant in the work. The viewer not just manipulates the images, but thanks to him, the whole piece is implemented.
