Computer graphics experiments led to examples where the graphical approximant is ambient isotopic to a spline, but a slight perturbation of the approximant destroys the isotopic equivalence. These serve as cautionary counterexamples for dynamic visualization of molecular simulations. These visual experiments facilitated the creation of a new operation on splines and formal proofs of its converg...
