Around the room there is a line created by electric wire, speakers and weights repeating the shape of cardiogram line. The sound: heartbeat getting slowed down to the unhearable level. The floor is covered with a layer of sound-proof sponge. 

Strong light in the middle creates shadows so that the line goes through shadows of viewers. Shadows of the line in white frames on the wall are drew over with pencil  which with time shows the differences in the position of the line. In the door the line goes underneath scale which visitors have to pass entering the space.
