Helvetia’s Dream "takes you on a nighttime journey to some of the most beautiful spots in the Swiss Alps – from Arosa to Zermatt, including the world famous mountains Matterhorn and Eiger." It's a time-lapse project about Switzerland by night. "Short videos of long nights present you the stunning beauty of the Swiss Alps and show you the magic of a spectacular nighttime sky. Imagine watching a slide-show at fast speed or looking at a flip book. It is photography turning into a movie. Everything in the videos is real and happening out there while most of us are sleeping."

On the Vimeo page there is quite a bit of text (in German and English), with highlights and interesting points in the video explained. On the video's own web page, you'll find a list of all the locations where the pictures were taken. I recommend you watch this video in the full-screen, HD versions on the Vimeo page - it's stunning!.
