When I obscure the true image on the left side, it's very hard to predict the truth from the computer/brain imaging on the right. With one exception: the tech does a mighty fine job with geometric shapes. (I wonder how it would do with playing cards.) Oddly, with non-geometric images, I see a lot of faces (especially dog faces). Is the brain prioritising facial recognition? Is the subject a dog lover? Do the two recurring dark spots represent the eyes' blind spots? I dunno, but I find these demos remarkable.
