This amazing screen saver captures the beauty, and grandeur of Yosemite in full 3D. The lighting effects are spectacular as the sun sets, and moon rises. Day turns into night, and night into day every few minutes. As you sit back, and enjoy the soothing waterfalls, you can almost feel the breeze as flowers sway in the wind. The vista includes El Capitan, Bridalveil Falls, and Half Dome. These landmarks are scale models created from US Geological Data, and photographs. Free 15 day trial.
