I am a great fan of science fiction art and I can appreciate the different styles from the genre's various eras, but I think I am most fond of this sort of stuff from the 70s, perhaps because that is when I was first starting to devour sci-fi in earnest around then.

If I grew up in Japan, this is probably the sort of far-out stuff I would have been geeking out to at the time.

It's interesting to see how sci-fi art has evolved since then. These examples of futuristic cities are good examples of the sort of digital art that is in fashion today. More examples of modern science fiction art can be found in this collection of DeviantArt wallpapers and if that doesn't satisfy you, browse CoolVibe's archive of Sci-fi Wallpaper of the Week entries.
