Ya know what would be cool? Stationing two cameras 180 degrees apart in solar orbits many AU in radius, and coordinating both cameras so that they always point at same piece of the sky.
Imagine the sense of depth and three-dimensionality you'd get looking at the pairs of images, as if your eyes were several AU apart. You wouldn't perceive space as just dots painted on the inside of the sphere, you'd see a volume of space with objects closer and farther away.
The scope of the effect would depend on the baseline between cameras, and maybe a few AU would only give perspective on our local volume of space. Someday, maybe we can take images separated by light years, and experience our galaxy in three dimensions. Wouldn't that be just exquisitely cool?

...but a very long baseline helps
