VECTOR is part of an ongoing series that explores the role of tools and tool-making within design investigations. It is an array of 2D and 3D objects consisting of multi-layered, monolinear letterforms connected at anchor points with elastic strings or fabric. By borrowing the logic of interpolation, it began as an exercise in deconstructing the forms of the flat nib pen to investigate the relationship between parametric parts. By connecting the layers with equidistant strings and fabric, the tool grants one the ability to dynamically manipulate the points, lines, areas, and volumes via movement. Through its inherent material resistance, VECTOR provides kinaesthetic feedback to specific actions (rotation, displacement) and intrinsic typographic properties (min-max distances, weight, contrast, etc.). As such, the resulting formal studies are an iterative, embodied process of unearthing vector relations within physical typographic forms.
