Rivulet

Here's the gutter next to the library after a storm. I noticed it just after I took yesterday's picture and thought it would make a nice black and white image. It had been rainy and grey nonstop for over a week when suddenly the weather made a complete turn for the better in a matter of minutes. This was the first time I had seen the sun in days. It made even a gutter look pretty.

I know it kind of looks like the water is running toward you in the photo, but actually it's running the opposite direction, "upward" -- an optical illusion.
