Title: Ferro — Invisible Forces
Exact creative prompt: Create a bold interactive magnetic direction field in burnt orange, ochre and dark graphite. Use a narrow orange left control rail with dense sans-serif display text “Feel the pull.” and a huge pale-ochre canvas full of individually oriented short compass needles. Calculate the direction from a source/sink point-pole approximation, draw labeled poles, and allow pointer dragging of one pole. Include keyboard-accessible horizontal position and visual-strength sliders plus polarity reversal. Explain that this is a visual approximation. Responsive, high-DPI, fully inline offline HTML5.
Description: An industrial material-study interface makes an invisible vector field tangible through hundreds of tiny directional marks.
Major visual techniques: Canvas vector-field evaluation; individually oriented needle strokes; labeled magnetic poles; ochre/orange contrast; narrow editorial control rail; technical annotation.
Intended interaction model: Drag a pole or move it with a slider, adjust needle emphasis, and reverse the source/sink polarity.
