Visiting a Nature Reserve in the center of France, I noticed that there was a lot of floated wood near the river. I wanted to work with this material, near the river. Te idea is to put the driftwood back into the river, so that it can continue its journey on the water. I wanted to respect the wood and not taking it back to my place. I made three "small boats" and I wrote instructions on the sailboat before releasing it on the water. If someone finds it, he can build it, make it better and put it back in the river for someone to find it ... It's an interactive and anonymous game. This project was carried out in this Nature Reserve. I also screen-printed two wooden signs to explain and show the project to the visitors if I wasn't around. At the reserve, children and families made the driftwood boat in the summer to clean the shores.
