Well I'm going to assume that most Macy's are the same, so there's many windows to display. But the one I work in, we've got an interactive Train Set. Customers can push the button and make the train move- it's actually quite pretty.

If you're talking about the Downtown Minneapolis 8th floor display, this is from their website: Macy's Minneapolis 46th Annual Animated Holiday Show and Santa Claus at Macy's SantaLand! Macy's Minneapolis 46th Annual Animated Holiday Show and Santa Claus: This year's theme, "A Day in the Life of an Elf at Macy's SantaLand" will tell the story of Santa's elves at the North Pole as they prepare for Christmas. Auditorium guests will enjoy seeing what happens in an elf's life from waking up and getting Santa's mail to teaching the reindeer how to fly and learning about Christmas traditions. The animated display is free to the public. At the end of the display, guest swill find Mrs. Claus' holiday bakery and Santa's Toy Store. Visit this family friendly shop filled with fun games, unique toys and great gifts, plus fresh gingerbread cookies and many other delicious holiday treats you won't want to miss! See below for Auditorium and SantaLand hours. Santa Claus at Macy's SantaLand: Santa Claus will make his annual appearance to gather the holiday wish lists of children across the land. Be sure to ask his elves about the various photo packages available.
