Ten Original Signed Harmonograms

These Harmonograms are beautifully rendered with black India ink on brilliant white 8.5" x 11" 110# cardstock. Each drawing is a signed original and consists of a single very finely drawn line. The Sample Pack includes vibration figure examples drawn with the Twin Elliptic Pendulum, Two-Pendulum Harmonograph and the Lissajous Figure Drawing Machines. Due to infinite variations in the motion of conical pendulums, no two continuous curve renderings are ever exactly alike!


I would be happy to produce a custom harmonogram order to your specifications and I offer a harmonogram framing (matting) service.   Please email me at if you have any questions or require anything special.


Sample Pack of ten different signed original drawings; $10.00 plus $3.50 shipping (USPS).

Each unique vibration figure is suitable for framing.
