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? |
