Tropic Waterfall is an animated image you can use as desktop background wallpaper on your computer.
The image represents a relaxing waterfall in the middle of a dense tropical forest.
Animation represents water falling from the top, while the accompanying sound adds a touch of realism. I guess the sound effects can get a bit annoying but luckily you can turn them off in the wallpaper's settings.
The main drawback I see to this wallpapers is the fact that it's not optimized to display icons; the image takes almost the whole screen and shortcuts are hardly to see when put over that much graphic detail.
