In this experiment, the audience draw a fine line in a virtual space using a computer mouse. The line starts from the bottom of the gallery and accumulates in the black wall of oblivion. Then, the accumulated drawing is precisely converted into the vibration of the speaker generating sound. This drawing action continues through the whole exhibition. We have only one chance to draw. No modification is allowed. With only one trial, we get only one result. Can we manage to make any meaningful sound from this experiment?
