Below, find the smooth time change of a linear flow. In the first GIF, the red points move with the linear flow, and the green and blue correspond to slow-downs of varying degeneracies. Notice that the orbits eventually re-align! In the second, you can see this slowdown affects a box in linear flow on a torus.

Below find a fundamental domain of the modular surface, and periodic horocycles on it sampled at 4000 points. In the first animation, they move ``downward'' in the Poincare disc model by applying the geodesic flow, eventually equidistributing. In the second figure, the half space model is used (rotated from standard conventions), and you can see the points distributing the the hyperbolic volume (more dense closer to the bottom).
