Therbligs Apparel & Gifts
A therblig is the smallest unit of work-related motion. They were developed by ergonomics pioneer Frank Gilbreth (yes, of Cheaper by the Dozen fame). I have taken his symbols and created this image, available on shirts and household items for everyone.
These shirts have the therblig image printed on the front only.
Front Print Only
The Therbligs image only
These shirts have therbligs on the front, and a quote from Robert A. Heinlein on the back:<br> Minimize your therbligs until it becomes automatic; this doubles your effective lifetime — and thereby gives time to enjoy buterflies and kittens and rainbows
