Nokia Beta Labs has an interesting touch interface concept demonstration named Nokia Bubbles.
Nokia Bubbles associates functions to perform tasks like unlocking a phone by moving a key bubble to a lock bubble or calling someone by moving a contact bubble to a dialer. The twist is these bubbles are in motion on a touch screen. I wonder if this movement might lead to increased errors or even frustration. It may be one of those ideas that looks cool at first glance but loses its attraction over time.
