That is not new by itself, but after watching the making of this very nice short film, I must say that the director/actor has gone to great length to make it look authentic.
Instead of using a Steadicam like most movies, he used a Gorilla Pod by Joby, a tripod with flexible legs. Placed two on his cheeks and hold the third one to capture close to what you eyes actually see. I did not see either special lenses, only different types of short monopods to hold the iPhone in front of his face.
Looking forward to see the whole thing. You can watch the trailer below.
