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.
