Zero temperature dynamics of two dimensional triangulations of a torus with
curvature energy is described. Numerical simulations strongly suggest that the
model get frozen in metastable states, made of topological defects on flat
surfaces, that group into clusters of same topological charge. It is
conjectured that freezing is related to high temperature structure of baby
universes.Comment: 17 pages, 15 figures. 1 section added on connections between present
work and inherent structures ideas; 1 paragraph added in the conclusion; 1
