Click here for some interactive mathematics: an applet to visualize the geometry of fundamental domains for the action of cyclic subgroups of $PSL(2,\CC)$ on $\partial H^3_\RR$. Some fundamental domains in the interior of $H^3_\RR$ for this action are in a gallery.

An explanation of the background is available for the incurably curious; other pictures on this page are fully explained in my papers -- read them or weep!
