EVE Online, this is something you have to see -- especially if you're a lover of either science fiction or pretty things.
This Russian blog has a whole lot of cool spaceships from EVE Online that have been turned into all sorts of cool pieces of art. And yes, not all of them are necessarily "nature" art, but most are more or less -- with the major exception of a robot and alien from, er, Aliens. There's one that's even a sneaker! Although, we're personally fans of the apple, eagle and Star Wars images. They come in wallpaper format for your laptop or desktop and honestly, there's not too much more to say about them besides praise them. Mmm.... beautiful wallpapers.
