I have been recently contacted be a Museum of the city of Surrey in British Columbia, Canada. They were asking for permission to include my photo of a rather nice, and unusual advent calendar. Of course I complied eagerly, and asked about the nature of their exhibit: it is an interactive where they make 3d calendars, advent calendars, and the like, counting down to Christmas. It is the power of Flickr, and that of Creative Commons to enable so easy and stimulating intercontinental collaboration!
