Each of these drawing is composed of the same 20 hypotrochoid line plots. The drawing method and number of line plots is identical, what changes is the ball-point pen used to draw each one. Drawings measure approximately 10 inches in diameter, they are on 17×14 Strathmore 500 Bristol board.
Pens used were, from top to bottom, Schneider 775 Fine ballpoint ink which is the lightest, with finer detail showing; Zebra Surari 1.0 mm ballpoint emulsion ink which left ink hazing all over the drawing as the ink doesn’t dry as fast; and a Dong-A Anyball 1.4 mm ballpoint pen which is the darkest, least detailed drawing as the pen point is thickest.
