Unity + Flash + AR?

Does anyone know how this one is done: Honey Nut Cheerios Honeyway Train Augmented Reality game by Boffswana for Saatchi & Saatchi NY - YouTube
It says it’s done with Unity, but if you play it, then it’s actually flash. Does it mean they build it with Unity for Flash, but integrated FLARToolkit into Unity project? Maybe someone has a working sample of such approach?

Unity export to Flash work fine and it can be integrated with FLARToolkit.
