That's clever. Nobody can draw dark in AR, which means overlays on the world have to be too bright and shiny. Ellsworth came up with a use case where the AR images always have a grey background, the blank game board. So this is much more workable than the more elaborate AR schemes. Cheaper, too, at $299.
