Three dimensional quantum gravity with torus universe, T 2 ×R, topol-ogy is reformulated as the motion of a relativistic point particle moving in an Sl(2, Z) orbifold of flat Minkowski spacetime. The latter is precisely the three dimensional Milne Universe studied recently by Russo as a background for Strings. We comment briefly on the dynamics and quantization of the model. Stanley has made many fundamental contributions to our understanding of life in various dimensions. Notable amongst these is dimension three. Therefore, on the occasion of his seventy third birthday, I present him a reformulation of three dimensional gravity in terms of a point particle moving in a flat three dimensional spacetime.
