Each time you see a nice photo or interesting link on your friends' Facebook walls, you would probably click the "Like" button to give the person a virtual pat on the back. Wouldn't it be great to have such a button in real life?
That's exactly what the Facebook Like Button Stamp does. U.K.-based design studio Nation created the product, which is essentially a rubber stamp that lets you "Like" paper documents complete with the thumbs-up icon. It isn't in mass production, but the company seems to be assessing market interest before making this available commercially for sale. E-mail Nation if you are keen on the idea.
