Seeing the world from above sometimes reveals all kinds of unexpected images. Take, for example, the astounding geometric grace of the world's largest plant maze--10 acres-as seen by ace aerial photographer Yann Arthus-Bertrand. Sunflowers and corn are used to create new mass maze every year at this site in Reignac-sur-Indre in France. Or how about Yann's photograph of this amazing heart-shaped clearing in a mangrove swamp in New Caledonia. These two photographs are but a sampling of the nearly 2,000 spectacular aerial images from all over the world available for free as wallpaper from his website. Thanks to his largesse, you could redo your wallpaper every day for almost 6 years. And get a whole new view of our world in the process.
