Abstract
Pendulums which swing in two dimensions simultaneously and are designed to leave a record of their motion are termed `harmonographs'. The curves which they draw are known, alternatively, as `Bowditch curves' or `Lissajous curves'. A variety of designs of harmonographs have been invented over the years. These may be a `Y-suspended' `simple' pendulum, or they may be a complex `physical' pendulum system. Harmonographs have been built as demonstration apparatus in physics (or mathematics) or as `art' machines for enjoying the aesthetics of the curves produced.
