title: Take a screenshot every hour with cron
body: <p>I just discovered the site of <a href="http://okayfail.com/2011/nytimes-timelapse.html" rel="nofollow">Phillip Mendonça-Vieira</a> who has inadvertantely taken a screenshot of the NYT twice an hour for the last year. </p>
  
  <p>Anyone know how one could do this? I think it's a fantastic 'accident' he came up with. Just the basic idea would be great — I don't really know how you might even do this at the moment.</p>
  
  <p>Thanks!</p>
