Allow me to explain. A while back, I was thinking about 3D desktops/window managers - specifically, the practicality of creating one in which the windows are arranged around the user in a rough sphere at varying distances. I decided it'd be a cool idea, but interacting with it using a mouse would require way too many non-intuitive modifiers - especially if you wanted to be able to (say) tilt windows out of the way.
After considering further, I decided it would need a fully-3D six-axis input device. (Imagine if you could move and tilt windows in 3D using simple, intuitive gestures with your input device. Want to pull one closer? Push a button and pull the input device towards you. Tilt one? - just twist it in the direction you want.) Realising that there was no way I was going to be able to build one (and that I was too lazy to try), I abandoned the idea.
Then the Revolution came - with a fully-3D, six-axis controller that was almost exactly what I was looking for (except apparently better than I thought was possible). It was even wireless and one-handed. Is this the controller fully-3D window managers have been waiting for? Any comments?
