Contour Lines

This piece is an example of a piece that is done using contour lines.  The lines in this picture create outlines that give the viewer a shape to view.  The figures that the lines create do not have any shading but instead include more lines to show how the shapes of the objects have been changed over time.  There is no thick border on the outside of these figures which is why the lines that form them are contour lines and not edges.  There is a hint of shading under the objects which look as if they were done using a stippling technique.
