I wasn't able to download the video (no seeds, that and bittorrenting anything has always been a headache with my router) but the stills are amazing. I have my doubts that my computer could even play it, it had trouble with a regular HD video I downloaded once. The stills have that flawless, creamy quality that just begs to be sharpened and punched up a bit. That look is usually what you get from drum-scanned film. I'm just blown away that something that large could be shot continuously. I did see some stuff about it on YouTube. At one demo they claimed they were using the only 4K projector in the world. Sounds hugely impractical in terms of bandwidth, but I just think it's cool that there's folks pushing the boundaries into insane resolutions. Who knows if these guys will succeed. Perhaps one day the detail will be so high that we will be able to suspend disbelief in the visual illusion as we sometimes can with the audio illusion today. We might wonder "Is that a window or a screen?"
However, we might ask ourselves, is it really that desireable to see every hair and crag on someone's skin? Could too much resolution be a bad thing? Hmmm...
