Bennett's Linkage
Another example of an overconstrained mechanism is Bennett's linkage, which consists of four links connected by four revolute joints.
A general spatial linkage formed from four links and four hinged joints has mobility
which is a highly constrained system.
As in the case of the Sarrus linkage, it is a particular set of dimensions that makes the Bennett linkage movable. Below is an external link to an animation of Bennett's linkage.

“Those who have known the famous are publicly debriefed of their memories, knowing as their own dusk falls that they will only be remembered for remembering someone else.”
