Go here for the animated version, and here for a video with these spirals.

The orbit of the group SL_2(\mathbb{Z}) in the Poincare disc:

Shown below is part of the orbit SL_2(\mathbb{Z}) g (0), where we let g\in SL_2(\mathbb{R}) change over time. On the left g is in the diagonal group (which is why we see geodesics) and on the right it is in rotation group SO_2(\mathbb{R}) which is why we see circles. Go here for the interactive version.
