S2H

Ok, this idea, I like.
Take a look at the S2H - really a good idea, i think. You wear this little wrist watch device during the day and it registers how much you move. The more you move, the more points you get. The more points you have, the more you can trade in for real physical goods. Or digital goods. So I am liking the idea that if I wear this this thing at the gym, i rack up points that I can trade in for itunes goods. Or other things. And it doesn't even look half bad. In fact, kinda cool.
The website is here in case you are interested in reading more about it...

It was created for kids mainly. Like the kind that just sit on the sofa all day and watch tv...
