Just to check that I'm responding to the experience as it's intended to be: On my machine, I saw distant trees rendered over nearer ones. If that's the intended effect, then well and good!
And it's an interesting effect! It feels a bit like looking at stained glass.
I'm not sure of how well it would work with other objects present--the background is quite busy--but as it stands it makes for a neat visual experience, I think.
