Toronto's CN Tower has a nightly "strip" of lights that change and flow, etc. Sometimes you can detect movement, and that is because quite often it is actually showing slices of an image. This is what it looks like when you make a stream of the lightshow. As far as I know, they never copyrighted it, and it is a super cool way to celebrate various events. For example, on Remembrance Day it shows poppies and other related images. On Canada Day, lots of Canadian images from across the country. https://www.youtube.com/watch?v=rqFMbXMfS9Q https://www.youtube.com/watch?v=rqFMbXMfS9Q
