I don’t want to turn this blog into a series of trailers, but I found this today Ghost Wire.

From what I can find out, in Ghost Wire players use the camera functionality in the Nintendo DSi to find ghosts that are superimposed over images of the real world that is displayed on the screen. Turning the local neighborhood into a kind of interactive haunted house. Obviously the quality of the experience will rely heavily on how the game actually plays but it certainly inspires a lot of possibilities.
