I've came across this Tap project that sponsors will donate every minute of idle phone usage to 1 day of clean water to the needy. You can visit it at http://tap.unicefusa.org/ for more info. I'm just proposing an idea that if someone can develop an app, or make a browser extension so that on a PC it can do the same thing. I'm not against the idea of not touching the device, but their approach is too stupid. The screen must stay on and blah. It's even better if we can game the project (if you know what i mean), because why not? If the sponsors want to donate they will, and we will help them donate.
