Here's the story- ok, so my brother is staying on my couch for a couple a weeks. Well, two days ago, I set up an account for him, enabled parental controls, allowing him to only use two apps; Garageband, and Safari. EVERYTHING else is blocked, and I logged his Websites... Well as you could imagine, a guy with no girlfriend, who may be home with a computer while his brother goes to work, can get... lonely. So here's the prank- I want to write a script that would automatically take a picture, about five minutes after he visits a certain website (which I'm only assuming is his favorite...), then make it his background, while not being able to change it. (I'm pretty sure it would just take a picture of his face...) I don't even know if this is possible... but i thought it would be hilarious. Anyone interested in helping me?
