Abstract
This expository note illustrates toric perturbation and biased pairing theory to show that Artinian reductions of face rings of -spheres that do not satisfy the Lefschetz property can be cut along a flat equator. This complements classical work of Bricard and Connelly, and exhibits a fundamental symmetry in non-rigid triangulations of spheres.
