I take more and more pleasure to work on square painting on the sand, the rendering often gives a more massive effect than the circles. It just requires a little more work, but visually the rendering is often at the rendez-vous on this type of drawings on the sand. I had a small idea in mind before arriving on this beach of Chay in Royan, but it became clearer once there and in particular to take sides to fill the bubbles completely. I had a little labor on hand with Guillaume, Manue, but also Thomas, a painter friend, who joined us later. So I took care of setting up all the outlines, as well as the exterior frieze, while the others gave their all to the filling with their rakes like gardeners on the beach. The work on the bubbles gives an effect of depth, seen from above we imagine diving into an abyss. It will take us a little more than 3 hours to create this new ephemeral painting between the rocks and the sea.
