not the first to come up with this as a sort of IK hehe, I have a few scenes of my own using this idea to position an end effector :3

Q: (You are) not the first to come up with this.
A: Probably not, but 2D RPR PKM uses the same idea. That scene was made 5 years before you made your first scene.

Q: I have a few scenes of my own using this idea.
A: You should provide links to the scenes so we can check them out. Else we would need to determine which of your 628 scenes use this method.
