Now as to the locii of the instantaneous VPP's, you've got me really confused here. Because the side links cannot 'pass' each other the points on one side of CL are mirrored on the other, tracing an ellipse. There cannot be any points behind the (whatever?) except on paper, where lines are of zero height (off the paper). These are great theoretical points but they don't appear to be meaningful, unless we have some EE's in the crowd dealing with imaginary numbers (square root of -1)
