There should be a law against not changing your default wallpaper if you're a hacker! You really spend hours and hours staring at a screen with that nasty bruise looking default Ubutnu wallpaper? Yuck! I'll be keeping this updated for you guys. I try to find ones that are hard to find too so these should be somewhat rare. Also, there are hidden Wallpapers in some of the articles that won't be copied here so if you want some really good ones, ya gotta read!!
