The folks over at GREENBULB have been working on an improved stylus for both the DS Lite the upcoming 3DS. It looks and works just like the one that comes with the system BUT, there is a catch. A simple flip of the stylus extends the length and expands the width at the same time, creating a feel akin to holding a pen or pencil. We will let you know our impressions and how it feels in hand when the product becomes available sometime in the near future. In the meantime, enjoy this video of Nintendogs and Cats using a prototype of the XStylus.
