    Came across some interesting animations here...test particle orbiting a black hole:

    I learned a lot from looking at the source code for that program, but was not happy with the "gravity well" animation because AIUI that should be a spacelike surface . . .
    Here is a similar but more advanced program, again with source available:
    GROrbits can also simulate light trajectories and those for black holes spinning in the equatorial plane.
    I use it as a check for my 4D geodesic simulations.

    Hmm, quite pretty, but a little too read-only for my tastes, not sure how I can learn very much from that.
