As part of the changes going on at MSN, a new addtion to the weather portal is promoting Windows Vista's new 3D-tab experience.
Over at the weather maps page, this Windows Vista advertising graphic is on the right hand side of the screen. Clicking it loads a flash application that allows the user to cycle through the weather maps in the style of Windows Vista's Flip 3D.
Mouse-over controls on the various maps cause the windows to cycle around, clicking a map maximises it. Not particularly practical, but "cool" advertising nevertheless.
Give it a try for youself at weather.msn.com.
