This is what you get when zoom in and move a camera backward at the same time. Up and down to move back and forth. Left and right keys to zoom in and out. Mouse to rotate. Space to activate/deactivate the Dolly Zoom Effect. When Dolly Zoom Effect is activated, moving forward is dependent on the zoom factor.
