Thinking about what feels different here, there are a couple of things that could be fun to implement:<p>- On iOS, opening and closing an app also scales and blurs/unblurs the wallpaper at the same time that it’s animating the app entering/exiting the foreground.<p>- Also, years ago, Apple added a very subtle 3D effect to the Home Screen. Essentially, when you’re looking at the Home Screen, as you tilt the phone, the icons and widgets move a few pixels in the direction of the tilt, which makes it feel like they’re popping out of the screen a little. To study the effect in detail, you can just look at the edge of an icon or the text below an icon and tilt the screen around and notice how it moves relative to the background image. It’s meant to be a very subtle effect, not some garishly dramatic effect.
