The house across the street from ours has one of these in the front yard. The owners put it out yesterday and left it deflated on the ground all day, but at night it came to life with light and movement. I even saw the guy who lives there taking some video of it in action yesterday evening. When Santa hits the top of the see saw's movement range, he does this little extra tip up like he's about to fly head over heels into the reindeer's lap. It's funny to watch.
I'm not sure I like his taste in Christmas inflatables, but I'm sure it will provide plenty of entertainment for the small people here in the coming weeks.
