Decorating the sky
Here is a fascinating short video from the NASA website Astronomy Picture of the Day of clouds and sky. There’s a full explanation about what’s going on in the video on the website, or why not just play the video from Vimeo which also explain about how it was put together. All I can say is that I wish there were as much blue sky here as there appears to be in San Francisco back in 2009-2010.
