The Yari is the first gesture-based gaming phone. It draws on the arm-flailin', good time-havin' concept of the Nintendo Wii for its control ideas.
The Yari boasts a 5-megapixel camera that allows the phone to track your movements when you're playing games. You can dock it on a bundled stand for side-to-side tennis and dancing games, or wave it in the air like you just don't care for other stuff.
Like the Sony Ericsson Aino, the Yari handset is currently only a prototype, but will most likely be troubling Father Christmas this year. Once you have the Yari, with its selection of preloaded games, you'll be able to access PlayNow, a kind of app store for games and music.

The gesture-based games function is somewhere between the PlayStation EyeToy and the Nintendo Wii. The camera records your movements when playing tennis or dancing, as here.
It's cooler than it looks, honestly. Look out for the boxing game, coming soon. This is still a prototype, but it'll probably be out in time for Christmas.
