OKNDrum: Optokinetic Drum
OKNDrum displays configurable moving stripes intended as an alternative presentation to an optokinetic drum.
Consider it only within an appropriately supervised professional context
Stripe color, width, direction and speed controls make the visual stimulus adjustable.
Keep in mind: The developer explicitly says it does not replace medical support; the listing does not establish diagnostic validation or equivalence to clinical equipment.
