The Spot by Clément Beauvais

Solidarités International et BDDP Unlimited veulent faire couler de l'encre
from BDDP Unlimited 

Clément Beauvais, a young director, illustrator, musician and photographer directed this campaign to mark World Water Day, building awareness of the scourge of undrinkable water.

I found the imagery in this video beautiful, such a subtle yet intriguing visual using water and ink.
