2-3 pendulum patterns may be swept through a large arc by the use of a rotary paper table, which rotates slowly relative to the pendulum movements. Harmonographs created with a rotary table are less common, but the designs are more interesting.
Alternatively, the paper table may move slowly in linear translation to produce a linear design (example at far bottom).
All designs or drawings below are created from a single, continuous line.
The computer-based designs may be swept ‘through phase’ produce a more dynamic harmonograph, as shown in this video. Choose full screen!
