I know the iPhone X is not out just yet, but it's in the hands of some media people and a few developers. I'm looking forward to getting it or getting my hands on it.

Here is my question. Do you see any uses for the hidden space behind the notch?

I saw that apps can render behind the notch, but it's not visible while the app is fullscreen, but if you go to the app switcher, the whole app is visible. Here is a little funny proof of concept. https://youtu.be/doEwhLtsACU

I thought about achievement-type games or puzzle games could use this, but its a once-off trick.

Do you see any other use for that? Probably people here are more creative than me :)
