Mystery Picture

I hope you are having a great Christmas. The kids are all happily playing (including some big kids who are having a refresher on an Atari Flashback console - Pong, anyone?). Supper isn't for another hour or so. I thought I'd share a photo my wife took recently. Do you know what it is? If you're taking a break from being social by checking blogs, why don't you post your guess in the comments section. I'd offer a prize, but I'm cheap and lazy.
