ASCII Signal Radar

A drifting glyph atlas describes a synthetic world signal while every click launches an independent expanding scan ring, brightening nearby operators before they return to the field.

• Product moments
• Spatial storytelling
• Interactive identity systems

• Procedural continent-like masks keep the glyph field asset-free and repeatable
• Pointer activity emits recurring scans while Randomize changes the scan language
• Ring width, travel speed and glyph drift remain independently adjustable
• Every scan modulates local glyph alpha instead of drawing a ring over the field
• Every control maps directly to this component's independent renderer contract
• Full-size and compact previews use the same implementation and behavior

Adaptive sampling, capped DPR and visibility-based suspension keep the renderer predictable. Test density on low-power mobile hardware before increasing it.

Pointer and touch coordinates are container-scoped; offscreen renderers stop work and pixel ratio is capped.

The visual canvas is decorative by default. Pair it with a semantic heading or description, and reduced motion holds a stable rendered frame.
