Would REALLY like to see that at higher rez. Reflections and depth of field look amazingly accurate to real-world.
Of course this skirts the whole issue of when you have something physical there it gives everybody on-set something to relate to in a way that imagination can't really deliver, even with SimulCam type on-set comps. Probably why there is so much more of a push to get away from greenscreen or minimize green in favor of getting more in-camera as of late. OBLIVION took advantage of 15K imagery -- 3 red cameras shooting panoramic sky plates -- to project backgrounds on-set in a way that looks unbelievably awesome and also at the same time provided all the lighting and reflection sources for the apartment in the clouds stuff.
