Just when you think you know everything and you've seen it all, the world turns up more unusual and interesting things. Heck, one of the things on this list was brand new to the world, or at least brand new to people, within the last year!
So, it's a good reminder to not take life for granted. There's always a good excuse to get out into the world and see it for yourself. You never know, you could turn up something nobody has ever seen before — or at least see something old from a fresh, new angle.
