Microsoft has shared a time-lapse video of the construction work of its giant Windows Phone display in New York City.

The video captures how workers erected a 6-story Windows Phone in New York’s Herald Square. The giant phone is being used as a promotional piece to market Microsoft’s latest U.S. Windows Phone devices. Microsoft is planning to unveil four Windows Phone offerings for U.S. holiday shoppers on Monday. AT&T will offer the HTC TITAN, Samsung Focus S and Samsung Focus Flash. Samsung’s Focus S and Flash devices went on sale in the U.S. on Sunday but the company has waited until Monday to reveal the HTC TITAN. T-Mobile is also offering the HTC Radar 4G.

Samsung’s next-generation focus includes a 4.3-inch Super AMOLED Plus display, 1.4GHz processor, 4G network support and a 1.3MP front facing camera. The rear of the device is equipped with an 8MP camera. The device appears to resemble Samsung’s Galaxy S II Android model. Samsung’s second Windows Phone 7.5 “Mango” device is aimed at the lower price point market. The Focus Flash will include a 3.7-inch Super AMOLED screen running a 1.5GHz processor. The device will also include a 5MP rear camera and front facing camera.

Microsoft is holding a special “backstage” Windows Phone event for media and press on Monday. WinRumors will be attending and Microsoft is rumored to be unveiling a Spotify application for Windows Phone alongside the HTC TITAN and other devices. Andy Lees and Joe Belfiore from Microsoft’s Windows Phone team will be on hand alongside a number of other Windows Phone team members.

If you’re interested in seeing the giant Windows Phone device for yourself then head down to the pedestrian plaza of Herald Square in New York City on Monday November 7 at 12 noon.
