click to enlarge the stereographic projection
This Wikipedia "featured picture" is a 360-degree spherical panorama of a beach in Marigot, Saint Martin, using nine images in a stereographic projection to create a globe. The assemblage shows the "little planet" effect, where the area close to the point opposite to the center of projection becomes significantly enlarged. A detailed explanation of how it is done can be found here.
The original image resides here on Flickr and was created in 2007 by Alexandre Duret-Lutz.
