You might have seen "Avatar" and been amazed by the 3D effects.

Now, at the Window of the World in Shenzhen, south China, the new OMNIMAX theater brings you the experience of flying in a cinema.

In front of the audience there's a huge 360-degree screen, in a room with a diameter of 30 meters. Even without glasses, audiences can enjoy a high-definition "4D" thrill.

The 90 seats in the theater ascend and decline as the film plays, and the audience gets a feeling as if they are in the scenes.

While the camera flies over forests and streams, the audience actually smells the aroma of the trees and feels the spray of the water.
