Indeed. You can see this clearly on modern wide-bodies at takeoff if you sit over the wing. The wings droop until the aircraft hits liftoff velocity--at that point the wings lift up and you are wheels up a couple of seconds later. It's close to 10 feet at the tip on a Boeing 777, where the effect seems particularly pronounced. It's also easy to observe wing movement easily during turbulence. I find it fun to watch but that's probably not to the taste of every passenger. On DC-10s you can also see the engines swinging on their mounts. That is a bit less enjoyable.
