This is the Microsoft PC Lounge at Saks Fifth Avenue. Looks a tad uncomfortable!
Also, Twitter. Microsoft is sponsoring a Twitter feed with the hashtag #HolidayWindows that runs in a window outside. The results are, um, interesting so far. Surely you can do better, try it.
Update: Microsoft says there are "filters in place to make sure that in opening them up to Twitter feeds we had content that was appropriate for the general public to view and was within the holiday theme. This filter includes any attempt to spam the windows with negative commentary that is not in the spirit of the holidays." So nothing nasty actually makes it up to Saks' windows, supposedly.
