Been hard at work on this one - now you can see the benefit of the Rift!
Hitting the target (skeet) is very hard, unless you look straight down the barrel of the shotgun - you can see this in the video where I miss the first four times. I think this very closely mimics the difficulty of skeet in real life.
I cheat a bit in the video below, by looking through the actual mesh, but you get the idea.
