Before I received my Rift I heard many say it was brilliant but I also heard some disappointment as to the visual quality. I assumed it would be good enough for me not to care (which is true) but there are probably many others who are also unable to 'just try it' and wonder what they can expect to see if/when they finally get to wear one. So I took the mirrored output of one race and made the following visual edits to give a rough idea (don't shoot me if it's not 100% perfect) of what the Rift is like to look through:
Yes you can see the black edges on the sides (you can actually see a little more above and below the edges shown here) but don't forget this image is hard up against your face and not half a meter away.
