Rotary knob
A hi-fi volume knob you turn in place; the LED halo fills and a tone rises with it.
Shape-Based · Original concept
The word is the track. Letters bulge and fill as the thumb passes over them.
Drag along the word; the letters swell under the thumb.
Tab to the slider, then ← → to step, PgUp PgDn to jump, Home End for the ends.
A native range input is the real control: it owns the value, the keyboard and what screen readers hear. Everything you see is drawn from it.
No libraries, just HTML, CSS and JavaScript
The concept
