GTA IV may be old news at this point as we all wait for some real information on GTA V or whatever incarnation the next game in Rockstar's open-world crime saga takes; however, Liberty City still has some tricks up her sleeve. A few hours ago Rockstar tweeted a link to a tilt-shifted bit of GTA IV machinima they found, and it's amazing.
Tilt-shift, for those that don't know, is a photographic technique that makes 2D images look 3D. It's makes GTA IV look like some kind of model train-set aficionado's dream come true.
