RollingMethod BC begins with a surface, which is then parsed, traced or divided to eventually inform marks on paper after undergoing some form of projection. Series BC-012 involves a parallel projection of the surface. Lines made up of straight segments are drawn vertically and horizontally within the space of the surface. Every other segment in each line is of a common length in three-dimensional space and is oriented normal to the surface. Intermediate segments connect the end of these segments to the start of the next segment, forming a continuous line across the surface. As the surface approaches flatness parallel to the "picture plane" (the paper) , the surface-normal segments approach zero length and the geometry of the line approaches that of a single straight segment. In run BC-012-001 horizontal lines are drawn with an aged but un-worn pen. Vertical are drawn with a fresh pen.
