CGI or no?

It seems nowadays its extremely hard to trust what you see on the television screen is reality. I don't mean reality television but the actual visuals. Computer generated images seem to dominate movie screens. Movies such as Transformers, The Great Gatsby, and even the hobbit rely heavily on post production imaging. Knowing this is what makes the band Travis' music video for the song Moving so captivating. For the video the band projected images onto their breath in sub freezing temperatures. To this day it is one of my favorite music videos.
