Most of you will remember that first moment you caught sight of Goatse, or Tubgirl (and I'm not linking to either, it's too early in the morning). Now there's a Mac program that captures the moment for posterity. Hello.app displays the offending image on your screen, and then uses your built-in iSight to capture the moment for posterity. Just the kind of prank to play on your kids at April Fools.

And you can use it with any photo, so this is a great way to show your wife those pictures of you with your new girlfriend and capture her reaction for the family photo album. I suggest leaving it on your desktop and renaming it "Firefox".
