01 / Strokes
Each stroke is a moving parcel
The field advects thousands of massless tracers through the wind vector at their feet, laying a fading trail behind each one. Fast air draws long, bright strokes; slack air leaves only a short scratch. Nothing is placed — the picture is the flow finding its own path.
02 / Passes
The gust lives at the gaps
Where terrain pinches the flow — a saddle between two ridges — the air must accelerate to conserve its mass. The strokes crowd and flare gold through every pass as gusts sweep across the range, then relax to a calm teal on the open ground below.
03 / Bearing
Sound the wind anywhere
The corner instrument reports the wind the way a station would — the compass bearing it blows from, in knots — sampled live at your cursor. Move across a ridge and watch the needle back and veer as the terrain bends the stream around it.
