cyclegraph
A photograph produced by attaching tiny lights to a moving person or object and using a long exposure to see the path of movement.
But this cyclegraph of Barnes, made by Frank B. Gilbreth for Walter Camp and Golf Illustrated, disproves the maxim utterly.
Where it comes from
Coined by Frank B. Gilbreth as cyle + graph to highlight the repetitive and cyclical nature of the work processes he was photographing.
