parametric grasshopper wall... the thick lines would be shelving system drawn as needed... these shelves control lines ("grain") routed into a plywood back. The shelf control lines can be any number and type (polyline or spline).... the tightness of the grain pattern is variable as is the relaxation or tension of the whole wall to match the shelf control lines.
