Browsing through the new apps this morning, I found this- Kirk's Communicator. Yeah, it's fairly simple and silly- OK, very silly is probably more accurate... but it's also a riot for an old-school geek like me. It would be really cool if it did more than just make sounds and were a real 2-way radio or the likes... but as it is everyone I've shown it to has loved it, and for $1 I can't really complain.
