Our intention with this experiment was to create a hexagonal grid within the tile boundaries which could be universally distorted to create topography or other dynamic surfaces for de-centralized irrigation to the edges. The channels for water flow are derived from this grid using a simple script and are embedded within an undulating surface so as to appear and disappear with the changing elevation. Through triangulation, we were able to manipulate the vertices of the grid independently in order to provide pathways for the flow of water, and allocate the zones for collecting and dispersing the water to neighboring tiles.

Using the Delaunay triangulation as a springboard for scripting, we positioned outside vertices of the geometry at the prescribed exits points for the water flow. The interior of the triangulation was populated randomly, but with an emphasis on creating a decentralized pattern. We then deconstructed the mesh in order to prescribe the simple rule that additional curves should be introduced for each side of every triangle, and that their geometries should be defined using the end points of each side and the centroid of the triangle. Hiding the original triangulation, we further disguised the underlying hexagonal grid and established the basis for our water flow.

The primary goal was to design a kinetic structure that is supported by crossing elements of the same material to each other. This ultimately created a self supported free standing structure with the help of crossing components.

We created several axes by grouping rods together to make the flexible components more durable. To achieve a durable structure that would support itself, we used two three-pieced rods and one four-piece rod. We joined all of these elements with by designing 3d printed joints.

There is a one-hole joint, three-hole joint and a four hole joint. Using the laser cutter helped us attach the joints to the board precisely.

The initial idea was to cut the wood in strips and develope a three-dimensional structure by joining them, in order to minimize wastage and take advantage of the natural properties of plywood. The concept stems from native basket weaving techniques which can be used as a structural system to develope different kind of three-dimensional volumes. Firstly, we experimented the material properties for warping, bending, joining and twisting. We tried strips with different lenght, width and fiber directions to find the best performance of the structure. After assembling the main grid, we reinforced the tower with longer pieces gradually. We discovered that the joinery we designed gave the structure possiblity to grow in height by pulling it in the longitudinal axis, and the diameter was contracted. We could get the opposite effect of expansion of the diameter resulting in a shorter tower. The form has the flexibilty of changing the shape without any adverse effect on the structure.
