About

Each image is the product of one of my self-made drawing machines, called a Pintograph, where different motors work together, rotating at different speeds, to drive a single pen. The artist controls all of the motor settings, as well as when and where to start and stop a drawing. The result is an incredibly diverse range of possible outcomes--some chaotic and messy, some harmonious and mesmerizing. Drawings take anywhere from several minutes to many hours to draw, and all resultant drawings are capable of being mathematically derived.

The red insignia in the lower right corner of each piece of artwork indicates the relative speed, setting, and direction of each motor wheel for that particular drawing; often times very minor differences in settings can yield drastically different results.
