Nice editing, with the footage of inquisitive smaller human near the beginning and the "Good job, papa!" at the end...
One additional functionality I think you should have - for those competitors who don't fully grasp the "touch free" aspect, maybe an "Ouch, hey, careful!!" in an extra loud voice for those who smack the finish box. Tied to an accelerometer?
Can you use the male Australian Siri instead? I use it on my phone because he's sexier.
Jim> SI should add that to the boxes. If they're in touch free mode and they get hit, it should cancel the punch...
The (surprisingly deferential) munchkin was a nice touch. But great engineering, biggins!
