Picture in Picture mode is a cool new feature for the iPad on iOS 9. As we showed you earlier today, you can even take advantage of Picture in Picture mode on the iPhone, if you're willing to jailbreak.
But what about the Mac?
Fortunately there's a Mac app called Helium that does a pretty good job of emulating the Picture in Picture effect on the desktop. It's especially handy for watching YouTube videos. Watch our hands-on video to see what I mean.
