GrayWall extracts mental labor in exchange for access to online information. I originally conceived it as a way to get people to talk to my lonely, elderly relatives for a set amount of time. The phone number above reaches an automated system that counts down from 5 and then grants access to the next page, though it could just as easily be set up to call my grandma (or perform any other task which can be timed remotely).
