Abstract
An apparatus for creating designs on a substrate such as a sheet of paper includes a frame with a platen mounted on the top thereof. The platen is loosely mounted for vibratory movement relative to the frame. A drive cam, through a link system, is connected to the platen to slowly move the platen in one direction and then rapidly move the platen in a directly opposite direction. A writing implement, such as a pen or pencil, is mounted in a generally vertical position on the substrate on top of the platen, to move with the platen as it is driven slowly in a first direction and then to move relative to the platen as it rapidly returns. The link means is selectively manually rotatable to permit changing the orientation of the vibratory movement of the platen and substrate.
