The device in both the image from Congo and MIB, is the
Spaceball 2003.
The black one shown in the MIB image is not painted, they also came in black. (I have 2.)
If you like to tinker and hack, the older models are readily available on eBay for very reasonable prices, but keep in mind that only the models currently in production are supported by the factory drivers. Older models will want to stay in linux and use the
spacenavd open-source driver.
The factory beta-drivers -can- be made to act as a normal mouse, but only for the models currently in production .
They also have native support in GoogleEarth, so you can 'fly' your POV around the world.
Shameless plug...
