I recently bought a Samsung Gear VR to use with my SGS6 phone....and it blew me away. The 3D VR videos and photos - 180 degree or 360 degree - are amazing.
Unfortunately, affordable 3D VR camera rigs are still very expensive (example: at least 6 GoPro 3+ cams + rig + stitching software)....and that's cheap. Nokia have an "OZO" 3D VR cam for only US$60,000. Eeek!!!
There is hope on the horizon. VUZE plans to start selling an 8-camera 4K 360 /3D unit in August for under US$1000. That's the point where I think I will enter this market.

Anyone else playing with 3D VR? I note that Phereo supports Oculus 3D format. There should be some good crossover here....and that may draw more people to this site, too.
