This is cool! Using software from GestureTech, your phone’s camera senses motion the way an optical mouse’s sensor does, though the emphasis is twisting rather than linear tracking. The dart board appears on the screen, essentially on a virtual wall in front of you. Your job is to twist around until you’ve got the dart board centered, then tap the OK button to make the shots.

Now see me with tomato on my face.
See, it’s not just a momentary timewaster, it can also be a psychotherapeutic stress reliever: simply point your phone’s camera at the object of your loathing, snap a shot, then then hurl virtual objects of scorn at it.
