A recent find, posted on BlackBerryOS, shows that RIM, the maker of Blackberry mobile devices, may not be as asleep-at-the-wheel as some think. A patent has turned up which reveals plans for a rotating keyboard. If nothing else, the idea is certainly inventive.
Although from the below image it is still not clear what this would look like, it still speaks volumes to critics of RIM, showing they are still creative. The patent abstract describes keys rotating from portrait to landscape, although it goes on to describe that custom layouts may be possible.
For the full patent, here is the link.
