Videographer Craig Shimala says on his Vimeo page that he had a bunch of timelapse bits and pieces of the Chicago skyline sitting around and decided to put them to good use.
What we get from his efforts is this trance-inducing clip of clouds and water and time flying past out city - in mirror form:
Through the past couple years I've shot a decent amount of time-lapses of the Chicago skyline. I figured why not take all of those and throw the same mirror filter that was warmly welcomed by a lot of people on this.
Shimala has a bunch of other interesting Chicago scenes documented, so check out his work.
