Galaxy Y Duos smartphone. How to go about it? How about performing a cool light show on some dude's face? That's the approach of this spot brought to you by the Portugal wing of the hardware maker. The model in question reportedly had to sit still for "up to" three hours straight as his face and upper body were used as a canvas for the same sort of video mapping we've seen applied to the sides of buildings. The result is a little strange, a bit spooky and generally awesome, even if your Portuguese is a bit rusty. Check out the video after the break.
