First i have to tell you, that i am not the original artist of this beautifull wallpaper. I changed the logo and painted the eyes green.
Thats why i will quote ZennouRyuu ( http://www.kde-look.org/content/show.php?content=4451 ):
This piece was originally done by John Le (dragonkahn from DeviantArt) so kudos to him for a very fine piece of work, the homepage link for this has been directed to his deviant art page, so check him out for more awesome work (He does some great art for evangelion).
Update: Now you can download this Dragon with glowing eyes.I hope you like it ;-)
