This is VR or Virtual Reality, which makes objects look 3d. To start, shrink this page until only the program is showing, then put a piece of paper in between you and your device. Paper can be any size, but this will work better with printer paper that is faced the long way between you and the device. Make sure that the paper blocks your sight of the other side of the white line. *Use the arrow keys to move some objects around *Press space to change objects
