This is one of the best YouTube videos that I have ever seen. It shows a guy throwing a paper plan from a skyscraper in New York. There is something about the way that the little plane flies over the busy city without anyone noticing which is beautiful. The accompanying music is also perfectly chosen to leave you with a great feeling.
I have watched it a few times already and more than 234,000 other people have seen it. I really recommend watching this if you can.
