Instead of needing a huge motion capture studio to map people to shared realities, Frog Design is working on a mask to both convert the world you live in to one more to your liking (at least on the surface.)  It's a slightly different take on the world of "Rainbows End" but it also shows that there's a lot more interest in Augmented/Alternate Personal Realities than first meets the eye.
