This scene requires a Google Cardboard or compatible viewer for the best experience. They can be purchased on Amazon.com or you may find Google handing them out at conferences if you attend a tech conference of some sort. I have seen them priced anywhere from $4 to $40 depending on who makes it and what sort of features it has. (Plastic, head straps, adjustable, etc)
This scene is just a fun little test environment I created while teaching video game art at the Academy of Art in San Francisco California. At the moment there is no real purpose other than to enjoy the visuals and prove to myself that I can get an app published to the google play store. I plan to make more Google Cardboard games in the near future and those will have more interaction.
The sensors in your phone track head movement to look around and to walk just look down slightly.
Hope you enjoy this little scene.
