Clarion is an experimental design tool that turns 3D body movement into drawing.​ Inspired by performance artist Heather Hansen's practice of downloading physical movement directly onto paper, the tool treats each drag as a mark-making event: velocity shapes line weight, speed shapes opacity, and strokes accumulate like charcoal on raw paper.

​

Using MediaPipe hand tracking through your webcam, the tool reads 21 landmarks per hand — capturing x, y, and z depth in real time — and translates that movement into accumulating strokes on a virtual canvas. Velocity shapes line weight. Depth toward or away from the camera changes opacity and pressure. Hand openness modulates stroke width. Eight symmetry modes — vertical, radial, kaleidoscopic — let a single gesture become a composition. The spacebar decouples movement from mark-making, giving you full control over where a stroke begins and ends. Designed for pattern layout, textile research, and gestural surface design. Export as a transparent PNG, drop it anywhere.
