It’s a QR Code.  Basically it’s an elaborate bar code that can hold a crazy amount of information.  

You scan it with your cel phone and then it kicks you to a webpage, offers you a coupon for the shop across the street, really whatever you dream up.  They’re huge in Japan.

I’ve been racking my brain on how to incorporate them into my show. Any ideas, let me know.
