This game seems quite easy. When I know one of them is computer generated and one not, it's easy to pick the real one. Like a multiple choice question is much easier than otherwise.

I didnt get a single one wrong, and am now playing with the rule that I have to decide within a few seconds, still all right.

Still, they're pretty good, If one of the CG images came up by itself in the course of other business I wouldn't bat an eyelid.
