Zuckerberg tipped his hand, just a bit, during Tuesday’s Facebook F8 keynote. During a demo of the company’s vision for augmented reality — in the form of a pair of easy-to-wear, standard-looking glasses — he showed how you could have a virtual “screen” in your living room, bigger than your biggest TV.

“We don’t need a physical TV. We can buy a $1 app ‘TV’ and put it on the wall and watch it,” Zuckerberg told USA Today ahead of his keynote. “It’s actually pretty amazing when you think about how much of the physical stuff we have doesn’t need to be physical.”

That makes sense, assuming you’re into the idea of wearing a computer on your face (and you’re OK with Facebook intermediating everything you see and hear, glitches and all).

But it’s not just TVs. This philosophy could extend to smartphones, smartwatches, tablets, fitness trackers, or anything else that has a screen or relies on one to work. Zuckerberg even showed off a street art installation that’s just a blank wall until you wave the Facebook camera app over it to reveal a mural.
