I like how well this specific picture works for this puzzle. The coastline lines up perfectly with a square border. The cat's face is sideways. The two steps are the same color, so the rotation could be in one of two possible positions. It makes it just tricky enough to make the right answer not immediately obvious, but it's not so hard that there's any chance for being frustrated. Plus, it's a kitty.
