Impossible Backgrounds

Starting with last month's post, The Chess Waste Land, I moved the Featured Flickr Photo series from a fortnightly to a monthly schedule. This gave me plenty of images on my short list from which to choose. I chose the following.

The description for this image mentioned,

After: Rafal Olbinski. Chess photo is wallpaper.

Out of curiosity, I fed the image to the images.google.com service I discussed in Search Your Own Images. It told me, 'Best guess for this image: 3d chess'. One of the links for the image went to 4 Games Like 3D Chess for Linux (topbestalternatives.com), where there is a well known image of chess pieces on a sphere similar to the featured photo above.

In fact, further inspection of the two images convinced me that they were essentially the same. The other image is red instead of blue, but the same pieces are all on the same squares of the sphere. That must be the wallpaper mentioned in the description. Feeding the red image into images.google.com told me 'Best guess for this image: impossible backgrounds'. Can't argue with that.
