Interactive drawing machine that produces infinitely unique drawings

Built unlike most drawing machines, this harmonograph was designed for heavy public use and abuse at the Brooklyn Museum. It endured two months and thousands of drawings in the main entryway.

The harmonograph leverages three linked pendulums that swing at different frequencies to draw Lissajous curves. As these curves slowly repeat over themselves, beautiful, almost three-dimensional designs emerge on the page.

 
 
 

Objective:

To design and fabricate an interactive public art piece for museum-goers at the Brooklyn Museum. The piece must be accessible to children and adults at all art skills levels.

Result:

A playful machine that draws mesmerizing, overlapping Lissajous curves with each interaction. Users can keep their one of a kind drawings for future inspiration.
