I'm looking for the name of a device that I frequently see in many scenarios, specifically that of an office/library which can be described as having multiple rings that rotate in various directions. I was thinking it was a gyroscope or perhaps a celestial globe, but something tells me that it's not quite what I'm looking for. I recall that there is a movie production company which uses this device as their symbolic figure of their logo.

Wow, I didn't know that they had a different name! Been calling them gyroscopes my whole life! –  Manishearth Feb 16 '12 at 2:21
