More: Step by step into a black hole is a different presentation of the same computer simulation. More simulations that illustrate relativistic light deflection can be found in the contributions Four-dimensional ray tracing in a curved spacetime, The "Real" Einstein Ring, and Röntgenpulsare (in German). In the Interactive Black Hole Simulation you can "play" with light deflection by varying the position and the mass of the black hole. For more examples of how fast moving observers see the world, see Visual observations in high speed flight and the references therein.
