Love this one so I've added it. The concept is very easy for most GenAI models to grasp, but it requires a strong overall cohesive understanding. Rather unbelievably, OpenAI 4o managed to produce a pass.

I should also add an image that is heavy with "greebles". GenAI usually lacks the fidelity for these kinds of minor details so although it adds them - they tend to fall apart at more than a cursory examination.
