Great advertising, but I doubt they really want this - after all, a publicly funded dungeon would have to be open to the public.

I switched all my family's headphones to bone conducting ones. They're bluetooth only, so no wires. No earcups. No hinges. And... uh... sound quality is already what it is, so rarely degrades. Cuts out 90% of the problems on this chart lol.

You're confusing parallax for rotation. Set something on your counter, and take a picture of it with your phone. If you walk four feet to the left, and take another picture, it will be at a different angle of parallax. That sort of transition would be impossible (or at least, incredibly small) given the nebula's great distance to us.

On the other hand, stand in one spot, and turn your phone on its side and snap another shot instead. Now you haven't moved relative to the object all, but your image is rotated.
