I was having lunch at my favorite Thai restaurant when I happened to look out the window and see this cloud sticking out at an oblique angle:
I noticed the unusually straight edge -- as if sliced with a straight razor -- immediately. Strangely-shaped clouds happen to be one of my favorite subjects, so I grabbed my camera and --afraid of losing the shot -- took this image through the window (hence the rather grimy detail).
The perfectly straight edge is even more striking when the image is tilted 90 degrees so the cloud and the power line form a 'V'. Maybe the eye is accustomed to recognizing the shape of the letter.
