There was an old app for Mac OS 9 that actually time-synced the image with the time of day. I cannot remember the app's name, but it was perfect. It gave a feeling of being outside, even when stuck in an editing bay for long days. I had always hoped this would eventually take that approach, but none of them are ever long enough. I would pay to have better and longer movies, if offered. I wonder if people are too focused on seing the four hours in five minutes time that they miss out on the ability have their desktops bring them the outdoors indoors.
