Box Man 2015‑2016

Box Man is an out of body experience that uses a Google Cardboard head mounted display to enable you to experience your life from outside of your body.

You, aka Box Man, have strap a Cardboard (or GearVR or Daydream) to your head. A friend records/films you with a second mobile device, and this stream is then beamed in real time to the Cardboard on your face, resulting in real time third person perspective of yourself.

It's pretty trippy.

You can read all about it on its website.
