Knock to Unlock

Have you seen Knock to Unlock yet? It's been making the rounds - largely in part to the amusing promo video from Sandwich Video. It's a pretty impressively clever way to unlock your laptop, from your phone. Personally, I think I unlock my laptop maybe twice a day - tops - but there are others where it is more common and it might be fun to have such a mechanism to access their machine. At the very least, watch the video and give the app a try.
