Yowza. Where's a freakin' grain challenge when you need one? Excellent. 'Cept you gotta fix the rotation leftovers. Oh, never mind - Rob already pointed that out. And for what it's worth, it appears wonderfully on my laptop at the angle I currently have my screen. Even better if I lean back a touch... 'cept if I stay that way too long it'll make my back hurt. Looks like you had a very good time. I'm envious.
It's excellent; if I tip my screen (I only have a laptop; I know, sacrilege, but still), it changes. One way, there is more detail, but tons more noise; tipped another, and almost all the detail and light is gone except for the bright spot on the wall straight back, with soft light emanating from around it and light shadows of the people there . . . I could play this game all day :)
One quick question: did you rotate this? If you did, there's a slice of light left in the upper left and two slices in the lower right, both inside the border (I tried to see whether they somehow "fit," but if they do, I couldn't see it).
