Dutch design studio Studio Sophisti has created a light-based communication product called PiNG, a set of two lamps connected with each other through the internet. So, when one user switches on his lamp, it lights up the other person’s lamp and vice-versa. And when both users have their lamps switched on, they glow at their brightest. PiNG is a metaphor for communication between two people, with the lamps being used a channel to exchange non-verbal signs.

Take a look at its video below:
