“tip of something massive”

Forty minutes into this clip there is  a great discussion on the potential and problems with the Rift and other VR helmets: 

I got my Rift today and tried ParrotCoster. It runs just fine on a Macbook Air 2010. It is a really nice experience! Despite the screen door effect, low resolution, tearing and non existing positional tracking I am excited. The rotational tracking is very good and it does not drift.
