It might work on chains, but I doubt it. The links of the chain will probably deform too much, especially when the distance between the end points of the chain changes. It'll work perfectly for pistons, actually, B.L. Render uses a piston as an example in her book. It's a sort of inverse kinematics, without the hassle of setting up IK chains, and it is surprisingly light on resources. I'm rather happy I found out about it!

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
