Abstract

An attractive demonstration, observation of chaotic Lissajous curves originating from sound
waves, was presented for the general public. A simple experimental setup used in this demonstration
consists of an optical lever, a rotating mirror, and a laser beam source. This system can detect a
variety of Lissajous patterns without an oscilloscope. Thus, this system can be regarded as a budget
oscilloscope. The application to program-based learning in physics education is briefly discussed.
