Here are the new elements: 1 - something yellow 2 - something round OR circular 3 - the intersection of two walls In regard to the first element, something yellow, we'll be applying Esther's infamous 83% Rule. The second element is more conceptual than it might appear. When we say something round OR circular we mean an object whose shape is generally spherical or discoidal. It doesn't have to be perfectly round or perfectly circular, but it must be...oh hell, let's apply the 83% rule here too. The yellow element and the round/circular element should be two different things. In other words, a yellow tennis ball or a yellow frisbee counts only as one element. The final element is pretty simple: the intersection of two walls. That's the angle where two walls meet. Simple, yes?
