Even though Windows Phone 8 is in the oven and on its way, Microsoft still has a duty to sell all of their 7.x devices. We've already seen promotional stunts like the Free-Time Machine, which featured celebrity guests at several landmark cities across the United States. Now Microsoft is employing a less expensive, yet more direct approach if a WMPoweruser tipster is to be believed.

Said friendly stranger took photos of a new eyepiece at an O2 Germany retail store, which has been nicknamed the "Windows Phone Wall". No, we're not talking about a Lil Jon song. The Wall features three-dimensional live tiles that jut out from the backing, as well as phones for onlookers to play with. Several of these displays will be making their way to select retail stores in Europe, in order to add some extra promotional pizzazz to attract people to Windows Phone. Finally, the tipster says that the Walls will be updated to promote Windows Phone 8 devices once those phones launch later in the year.

Let's hope these displays are a sign of a renewed marketing effort from Microsoft, which has been their Achilles Heel so far in the smartphone market. You can check out one more photo after the break, and for another pic visit the source link below.
