The most fascinating shows are easy to miss. VR companies like Oculus are already trying to take immersive theater to living rooms, but the best experiences still remain low in tech and very site-specific, staged in real-world places, and kept mostly phone-free (I turn off my phone during shows). In a year where I’ve seen a lot of attempts at making augmented reality become a magical thing, this theater piece was probably the best augmented-reality experience of all.
