This is a great art project from Andreas Heikaus. According to Andreas:
This video was part of my Bachelor thesis at the University of Applied science and art Hannover. The Super Mario Bros. game, released on the Nintendo Entertainment System, is not longer bound to the television size and get interactive with a new environment. The emphasis of my thesis is on the matchmoving work. It is the process of matching CG elements into live-action footage.
It is like something out of a dream.
