Checkerflexes are called that because of their resemblance to the squares |
||||||||
|
on a checkerboard. They are built from square pyramids that are joined |
||||||||
|
together by equilateral triangle hinges. The hinges also connect these |
. | |||||||
|
pyramids to a backbone of hinged squares. |

Twisting any one of the pyramids causes all of the other pyramids to twist |
. | |||||||
| . | ||||||||
|
also. Each pyramid acts as both a hinge and a lever forcing adjoining |
||||||||
|
pyramids to twist. |
||||||||
|
|
|
|||||||
|
As the pyramids flex the entire |
||||||||
|
backbone structure flexes in one |
||||||||
|
direction. |

Besides being cool gizmos themselves, |
||||||||
|
checkerflexes can also be used to |
||||||||
|
power multi-leg critters, or wings, or? |
