A framework (G,p) is a graph G=(V,E) and a mapping p: V \to R2. We prove that if (G,p) is an infinitesimally rigid framework then there is an infinitesimally rigid framework (G,q) for which the points q(v), v \in V(G), are distinct points of the k * k grid, where k=\lceil {\sqrt{|V|-1}}\rceil+9. We also show that such a framework on G can be constructed in O(|V|3) time.
