You're not as special as you thought, Rainbow Dash.
This vector wallpaper thing is optimally suited for 16:10 displays (people running 1280x800 like me, or people with 1920x1200 monitors/televisions). I was going to make 4:3 and 16:9 versions of this, but it just doesn't scale and crop properly. Plus, I'm lazy.
The ZIP contains two versions: one with blur on Fluttershy (as seen above), and one without.
