It is certainly an unusual sky, my guess is that it is something that you would find in the ocean :D
On a more serious note, I'm always 'seeing' things in clouds, wood, fire, shadows etc. You see, when we were small my mom would play a game with us, we would have to make a picture out of clouds etc.... and hope it didn't disappear before you had showed mom and the other kids - we didn't get TV in SA until the late 70's :lol: and now that we have it I hardly watch it and have reverted to watching shapes :help:
