Finger clouds

I am walking home from work the other day and I look up and this is what I see. Four small clouds stroking across the sky. It was as if someone had run their fingertips through the sky, like you would in the sand. I instantly stopped to get my camera out. Luckily I had it with me that day. I took my photo and then moved along. Then I looked back from where I had just been and several other people were taking photos with their camera phones. Guess I wasn't the only that thought it was beautiful.
