Images- Wallpapers on Pi

After all, even if I'm not a graphic designer, I often look for beautiful images involving Pi on the web (I meant big images, or artistic...) There is no reason that I should be the only one! But I have to admit that this area is very poor maybe nonexitance...

Here is what I could find and my few trials, excluding the small images on my site, that I made about two third, and so that you won't find elsewhere (normally!) Such as the turning-Pi and the Earth on the home page, as well as the image above.

To avoid "stealing" what is best done with the sites dedicated to Pi in the world, which won't be right, I had chosen for a few years to offer tabs of the images, and a click on it would send you on the page where the image was. Unfortunatly, the web is so dynamic that many links stop working... I was forced to link directly to the image. The image's website is of course still indicated if possible. If an author does not like this sincere arragement, he should contact me.
