Virtual reality draws a clear line in the sand—you're in the real world, you put on this headset, and now you're in a different world. But augmented reality technology allows you to straddle that line, keeping one foot in both worlds and in doing so, creating a third world that's all its own

It's in this third world of augmented reality that Nexus's Invisible Museum lives. We already know that not all art is visible. But these works are less invisible than they are cloaked. They’re perfectly easy to see, if you look at them the right way, which is through a tablet device equipped with augmented reality technology.
