Each harmonograph drawing is a single continuous line that is several hundred meters in length. Drawings are made with fade-resistant pigment ink on 160-250 gsm paper (Canson, Dorée, Hahnemühle, HP).
Harmonograph drawings are grouped by year. There are also pages to describe the basic harmonograph types: Pendulum, Rotary / Linear, Lissajous.
