This is by far one of the best themes resembling upcoming Windows Se7en OS.
Theme is made to resemble the OS with minor modifications.
For 8900, Tour, and Bold Windows Logo is a static icon and cannot be changed but it features few points: 1) it activates the Application screen when clicked, 2) when scrolled Up gives you access to Profiles, Manage Connections, and WiFi options; 3) when scrolled down, gives you options for Calendar and Alarm. All the other icons are exchangeable to whatever you specify under Application screen
For Storm theme features homescreen with three static icons on the right and five (six including weather icon) user selectable icons on the bottom. Theme also has a hidden dock which is activated/deactivated by pressing shiny windows icon. Note: make sure your first icon on the application screen is set to a weather application (of your choice) otherwise the homescreen will look slightly different then on the picture.

Theme is available only for devices highlighted in green. To get your copy simply click on your device.
Below are some images of the theme. If you need more simply click on the BlackBerry screen for extra images.
Theme might not appear exactly the same on all devices.
