## Main Question or Discussion Point

Has anyone ever analysed Einstein's equations in 1+1 spactime dimensions?

It seems to me like this would provide a convenient toy model for teaching or learning general relativity. For one thing the spacetime curvature can be visualized as curvature of a 2-dimensional surface.
