Drawing made by tracking the left and right hand movements over a period of 15 minutes while working on a PureData patch to control the plotter :

Frank and Lillian Gilbreth, motion studies from their work as well as a quote from their 'motion study' book.

"Have you reason to believe that your workers are really happier because of the work that you have done on fatigue study? Do they look happier, and say they are happier? (If so) then your fatigue eliminating work has been worthwhile in the highest sense of the term, no matter what the financial outcome. Naturally, the savings that accrue must benefit everyone, but saving lies at the root of fatigue elimination, and if every member of the organization, including the manager and the stockholders, is getting more "Happiness Minutes," you are surely working along the right lines." From Frank and Lillian Gilbreth, Fatigue Study (Easton: Hive Publishing Company, 1973 ; reprint of 1916 ed.) pp. 149. from http://www.arts.arizona.edu/buildingbetterhumans/hm_2.html.
