That reminds me. I had a cunning plan at one time to use my swivel chair for rudder control, using an old gamepad as input, rigged somehow to move a joystick as the chair turned. I never tried it, and I suspect it might be awkward to use in combination with TrackIR. If I wanted to apply left rudder and look to the right, or vice-versa, I'd end up with a twisted neck...
