Water is Life
This is definitely one of the greatest speeches I've seen street, if not the largest, Water is Life by Henk Hofstra.
Water is Life, is like Henk has called to this work that in a few hours had already spread all over the Internet; thousand feet were painted by the artist in Drachten, Netherlands, making the cement and water and bring life back to a stage which had been killed since the invasion of man in these lands.
The most impressive is the detail with which he has worked since to give more realism embeds cars, poles and so on, so I leave you with more images of the good work.
