Harmonographs date back to the mid-1840s, a device used for education and art. They peaked in popularity during the 1890s. While we can’t credit a precise creator, Hugh Blackburn, a professor of mathematics at the University of Glasgow, is thought to be the foremost inventor.

 

The new Penduloz harmonograph is an advanced apparatus that uses pendulums to draw geometric images — typically Lissajous curves that give rise to complex designs.

 

The Penduloz uses two pendulums to control the movement of a pen relative to a drawing surface. One pendulum moves a pen back and forth along one axis, while the other moves the drawing surface back and forth along a perpendicular axis.  

 

Experiment with various calibrations to create ellipses, spirals, figure eights, and other Lissajous figures. Endless options and outputs!
