The original version of this deviation [link] was one of my first creations in Photoshop. It was done a long, long time ago, in an old, old version of Photoshop (5.5). Back then, 1024x768 was the de facto wallpaper resolution.
But as the clock ticked forth, screens grew larger and larger.
This high-res version should be able to hug monitors without stretching disastrously. At least until we're going to have ultra-super-HD.
Also, this all-new "revisited version" includes minor upgrades over the previous one -- better shadows, slight overbrightness and smoother curves.
