I have a Nexus 5X and trying this just crashed my phone. As in everything froze and then the device rebooted. I only tried one experiment[0] and couldn't even get it to run.

I had the same experience when I saw my first online streaming video many many years ago.

Your first streaming video was probably unwatchable. The problem with VR is that for a lot of people 'unwatchable' means serious headaches and nausea.
