A pack of 40 beautiful retina ready wallpapers for your iPad or another retina ready device. You can download the retina wallpapers and use them as background on any device though.
If you want at least a glimpse of the look and feel of the brand new iOS 7 which was released last week, you can help yourself with the wallpapers below. I took the originals (which you can find in this post) and cropped them a bit to be more suited for Windows or Android devices. The size is 1920×1440, so standrad ratio but it works well on widesreen devices also.
The 27 wallpapers above are included in the iOS7 upgrade for the iPad. The size of each wallpapers is 2524×2524. You can use the iOS7 wallpapers for any other device or PC, but if you like them better iI uploaded a cropped versions adjusted for PC, size 1920×1440 here.
