Thanks! That's made from two shots I took at the Shedd Aquarium a few years ago when they had their huge lizard exhibit. He was sleeping when I came up to him, so I took a shot. Then without moving anything but his eyelid, he woke up, so I took another shot. All I had to do after that was make an animated .gif of the two to make him wink.

Feel free to use it, if you like. :)
