The internet used to be filled with jokes for April Fool's, but that trend has been on the decline lately. Even Google, the company that would always do very elaborate pranks on April Fool's Day has backed off from it. Google did do at least one thing, however. Google Maps has a "Where's Waldo" game you can play. Google also announced "Google Cloud Hummus."
Bob wonders if the iPhone will have an eclipse easter egg. He had an Apple Newton during the last eclipse and the Newton had a little animation for it.
