Rocks are formed from continuous mechanical friction over millions of years. These series of surfaces invert the normal process and allow the rocks to exert themselves onto wooden surfaces. 3D renderings of round river rocks were used to impress into these surfaces many times allowing the negative space to create concave indentations into wood blocks. CNC machines then fashion these textures into the wood. This allows the natural visual rhythm of the rocks surface to become emerge on the wood itself. It also allows the natural grains of the wood to be exposed in a precise way that would be impossible through more traditional techniques via wood carving.
