For fun:

My daughter was in the bed, I snuck the N900 onto her bed, armed it, snuck to the room door, grabbed a ball of yarn, threw it and hit the N900 and shut the door........

She screamed aaaaahhhhhhhhh and much laughter and smiles all around!

That was priceless. Thanks offscreen and OP for making me aware of the app. All complaints aside, my N900 can do one more thing than it could do yesterday
