Using code similar to that in Parallax projects, I made the illusion you're in VR! I will add games soon, but at the moment it's just a room you can move around in. I made the room white because if it was a background, it would spoil the illusion. Also instructions are below.
Move your mouse to move your head. Your head will go the opposite way of the mouse. A and L to reach/grab. This function has more use later. Side arrow keys to move left and right! Left arrow for right, right arrow for left. Up and down arrow keys to move forwards and backwards.
