Okie, so I did a quick sketch of this back in, like, 2015, so technically, the title of this topic is a bit misleading but who cares? 
2015-ish was when VR was still in its infancy (though hyped AF), and I was thinking: “What if Apple decide to create the ultimate VR/MR/AR device BUT it is a one-way street a.k.a. once you put it on, you cannot take it off?”
