iPad Log in/Lock screen mystery icon...

[HX_Guy]

Does anyone know what the icon next to the slider is on the log in/lock screen? I've seen it a few times and haven't seen anyone on any of the sites mention it. Almost looks like a user icon/photo...possibly for multiple users?

Steve mentioned it during the keynote. It starts a slide show (turning the iPad into a digital picture frame).
