It came to us through BlackBerry Forums and there is a link to find out why the theme was developed and where to pick it up from. (The author actually took the background images which look absolutely fantastic).
The theme is available for 81xx, 83xx, 87xx and 88xx series devices and OTA or Desktop download. As I stated above, the theme is free but donations would be greatly appreciated.
Just hit this link for the expressway to heaven; Salvation theme (Zen)
