The machine is an adaptation of the harmonograph, a 19th century device that translates the harmonic motion of two or more pendulums into the rhythmic movement of a single point, or in this case, the tip of a pen.
The goal of the project was to apply the concept of evolution into a user driven machine. The machine can only create a harmonic drawing if the pendulums swing in harmony. This forces the users to work together and adapt to the rules of the machine.
The shapes produced by the machine are called Lissajous Curves, named after the French mathematician who studied the mechanics of the harmonograph during the 19th century.
Custom wood bench designed to fit around the structure of the harmonograph and allow the users to sit facing one another
This series of drawings shows the process of two users learning to work together. With trial and error, the quality of their cooperative drawings improves, and the game of evolution succeeds.
(My personal favorite)
This curve is the result of the users struggling to balance the pendulums
