I've found two nice pictures from my summer trip to France, where I shot this beauty.

It was really-really early (I took a train at 5:50) and I was blessed to watch the most amazing sunrise from the train's window. Was really challenging trying to catch the moment but I think I got it. And you see the balloon? So cool!

 

You can use the big picture for your laptop or computer and the small one for smartphone (actually size is adapted for iPhone 6 but I think it must be ok for the most popular types of gadgets).
