I like the concept, getting close to nature is good (sometimes) and 'we' (city dwellers) seem to have lost this touch.
I also liked the geometry used, on the last photo [1]. I believe that he started building by first putting the stone on the ground, then he used the stick (on the ground) to establish fixed radius from the center (stone) and ensure that he puts the "pillars" in equal distance from the center. It would have been easier if he was to use 6 (distance between two consecutive "pillars" = the radius) instead of 8, but I believe that would improve structural stability and slightly increase "building" surface.
