Abstract
The manipulator includes an internally toothed ring, an externally toothed wheel, and a cam arm. The wheel and arm, which function in a 'master' capacity, have registerable holes for accommodating the tip of a ballpoint pen so that a primary line design is created as the ballpoint pen is manually moved over a sheet of paper while maintaining the wheel teeth in mesh with the ring teeth. The ring has at least one pivot post projecting upwardly into a slot in the cam arm to cause the cam arm to function in a 'slave' capacity so that a fiber-tipped pen gripped by the cam arm produces a secondary line design at the same time the primary line design is being produced.
