Who didn't have the old cup-and-string telephone when they were a kid? It was one of those things that everyone had to try out at least once to see if it really worked, and who wasn't excited when they found out it actually did? Well, that excitement may have faded over the years, but that doesn't mean we can't appreciate some good old cup-and-string based gadgets today. Duncan Wilson's Cup Communicator brings that old-timey form of communication into the 21st century by cutting the string. The Communicator is basically a walkie-talkie shaped like a couple of cups with string hanging out. You tug the cord to turn it on, squeeze the cup to talk, bringing you back to the good old days. I'm not sure how often you use a walkie-talkie, but if it's more than never this would be a cool replacement for your boring black boxes. That is if they were for sale; this looks to be just a concept at the moment. Dang. — Adam Frucci
