Bought a VR headset for a bit of fun the other day. Managed to find a few apps but nothibg too exciting. Just like rollercoasters and 'scary' ones. Just wondering if there is anything better out there? Is there a possibility of using the rear camera (ie use your surroundings and things added to it) make it a little more interesting?

Try searching 360 videos on YouTube, Australia tourism has a great one underwater with seals.

I think 360 videos are going to be your best bet.
