The field decides the form.

Learn-it path — ART → CODE → LEARN → architecture

1. Build the field. At every point, take a smooth Perlin-noise value and turn it into an angle — an invisible grid of arrows that curves gently across the canvas.
2. Flow along it. Drop particles and, each frame, step each one in the direction of its local arrow, leaving a faint trail — they bunch into clean parallel rivers.
3. Layer it. Keep the streams fine and cyan, then send a few fat magenta ribbons down the same field (Fidenza's move) — hierarchy without clutter, hard-weighted to black.

NOW APPLY IT TO A BUILDING → the field is never just decoration. Seed it with a pedestrian or air-flow simulation and the streamlines become circulation corridors / duct runs; seed it with a finite-element stress field and the lines become fibre orientation for a printed or woven façade — material laid exactly along the load path, the same way a 3D-printed concrete or carbon-fibre panel should be reinforced.
