The Wright Bros had warping wings, and the Freewing airplanes move
thevwings together, in relationship to the body. There's a lot of research
into changing the shape of wings to provide differential lift. I don't
think anyone's actually rotated wings separately for roll controll - it
would be difficult. The smallest change in
relative angle of attack would give you huge rolling moments. I think
controlling it would be a non-trivial problem.

Over ten years ago now, I saw a Discovery Channel show where a guy put a PVC
type pipe on top of a small high wing planes' fuselage. He attached two
wings to the pipe - the pipe was sticking out each side of the fuselage. The
wings were free to rock and roll, independent of each other.

The reporter went up and pronounced the ride - smooth as silk. Also, the
plane now had super-STOL abilities. I think it was a story out of OZ.
