Yesterday I was waiting at a light and looked up at the clouds in the sky. The cloud formation directly in front of me had a perfect rectangle of blue sky in it and to the left were some much lighter clouds. It looked very much like a window with a shutter on one side. Unfortunately when I got my camera phone ready it was gone. They have a stairway to heaven, at least in the song, so maybe this was a window to heaven that was open just long enough for maybe one or two lucky souls to get there.
