Suggested wording for this test:

"There should be a circle with a diamond inside below. The diamond and the orange circle should be appear to be moving in a circle, around a common center point. The radius of motion of the diamond should be slightly shorter than that of the orange circle (measuring the radius to the center of each shape), so that the diamond is always near the side of the circle closer to the center of motion."

Bonus points if the test actually shows a dot at the center of the circle of motion.

The fact that it's hard to explain what the test should do indicates that it is not a good test.
