Another Walkie Talkie Watch, but this time not quite so nerdy looking. These watches were worn by the Norwegian Olympic Team during the last Winter Olympics, which means they're decent enough for people who need things to work—whatever that means. There's eight channels with 38 sub-codes, which makes for 304 discrete discreet channels. The 3km (1.86 mile) range is better than that other set of walkie talkies, but these don't come cheap—$109 plus shipping for a pair.

They look like they're nerdy but they made me and my friend feel like secret agents when we were plang paintball.
