Space curves
The initial inspiration came from a series of Harmonographs generated by Edward Lias in the 1960’s, published in Photo Lettering ‘Alphabet Thesaurus, Vol 2.
Harmonographs
A harmonograph consists of two pendulums and a means to record their compound rotation. In some constructions, the pendulums are separate and don’t influence each other, and in some one is attached to the other.
Compound orbits
There are similaries to the three body problem in physics, where a moon orbits two planets, or a planet orbits two suns.
Freely twisting
I felt that these diagrams looked three dimensional, so I wanted to understand how the surface would have to be stretched to follow such a path.
Anticlastics
Looking into the metalsmithing techniques required, I learned about the work of Heikki Seppa and Michael Good, who had done some wonderful work in the area.
