So I am sitting, waiting for my car's semi-annual check-up to end, and this guy walks by carrying a copy of the book Inside Star Trek by Herb Solow and Robert H. Justman (the show's producers). "Great book," I said. And then he stops to chat a minute, and shows me this.
It is a communicator that links to your cell phone. Best Buy sells them. They are super realistic, having been scanned from an original prop. I was wowed.
It chirps when opened. The whirl whirls. The buttons light up (and are used to answer the phone).
