Remember those giant pencils you'd buy as a kid, use them for a day in class as a joke and then chuck em before lunch? The SmartStylus is built on a similar premise.
Coming in two models (SmartStylus 1 & 2), the stylus is designed to add vibration feedback "based on movements and commands in the game." The SmartStylus 2 adds the possible integration of LEDs, sound and even motion (imagine swinging your stylus like a baseball bat).
We're a little confused as to exactly how the SmartStylus will integrate with games not specifically designed for the device (if it will at all), but those questions should be answered when it launches for an undisclosed price this fall. [Maxconsole]
