Dial the signs.
Change a parameter and watch the eyes respond. Turn a normal head impulse abnormal, flip nystagmus to direction-changing, add a skew — and see the central-versus-peripheral read update as you go. Copy a link to send any eye you build to a classmate.
Maneuver
Nystagmus
Spontaneous nystagmus is left-beating. It settles when the eyes fixate and flares when fixation is removed.
Pattern
Slow-phase velocity12 deg/s
Fixation

Realism0%
Real eyes never hold perfectly still. Add fixational drift and micro-saccades to see the sign the way it looks at the bedside. Purely visual — the read above does not change.
