As the Huygens probe descended, it took lots of pictures on its way down to the surface. Those are just a gold mine of information.
Here is a really fun movie that we call the "bells and whistles" version. It is incredibly information rich. I love watching this over and over. You can see little cartoons showing probe orientation spin, telemetry data, instrument sequences, and images. I love to marvel at the planning that made this happen.
