I couldn't possibly tell you where I found this, or why I love it to the extent that I do, but in case you haven't seen it before, please check out "the unseen video."
The concept behind it is that depending on date, time, geographical location, and current weather, the video changes. Check it out now, and check it out again in the summer months... it's a neat experience!
My favorite part is the shot of the hands... It's a constant in the video, so you'll see it no matter when you watch.
