The title of this series refers to the coördinates of a specific (fictive) place in space (x,y,z) and time (t). The drawings are an abstraction of the energy felt on that place.
The fine ragged sides of the torn paper sheets refer to both the fading edges of our field of vision and the fading borders of our counsciousness.
The drawings are made with multiple layers of charcoal on both front and back of the semi-transparant paper sheets. The drawings come about on a slow and layered manner.
