Está claro que Valve cada juego que hace crea adictos. Y no hay nada más que ver a los que se han currado este corto mostrando en funcionamiento el arma de Portal que crea... portales.
Esta es la descripción que hace del vídoe su creador, Jason Craft, en vimeo.
My interpretation of what a real POrtal gun would be like if one existed. Based on the video game, POrtal. I tried to match the game as close as possible. This was the most challenging project I have ever undertaken, consisting of 3D tracking, seamless camera cuts and 3D camera projection. This started out as an experiment since I didn't think I could even pull it off, if I knew it would've turned out as good as it did I would've put more of a story behind it. O well, it makes up for in Visual Effects, ENJOY!
