Seeking Cheaper VR

Colleague Walter Riker demonstrated the use of 'cheap' VR using 3D visualization from a smart phone, which you attach to your head with goggle like glasses.  The glasses combine two images which are displayed on the phone, which creates the illusion of 3D.    Akin to the ViewMaster device, but one that can be modified dynamically based on the movement of your head.   Clever idea that works relatively well.
