Here's a simple little scene file ( and QT moov.) that shows background starfields that allow camera movement. This isn't pasting a simple starfield PICT into the background, but a real live scene that has stars throughout the universe in all directions. So when you pan your camera, the stars move as in real life. (Well, as real as it gets.) A real easy way to put those logos into space and add camera movement. Also cool for spaceship renders and such.
No, it's not the most original idea, but it's here, it's free and it's easier than doing it yourself. If you're lazy like me, that should be enough. :)
