<think>Target shape: cyan square at (6, 1)
Distance from target shape to orange square at (3, 3): 5
Distance from target shape to blue trapezoid at (3, 4): 6
Distance from target shape to yellow rectangle at (4, 7): 8
Distance from target shape to green square at (0, 7): 12
Closest shape is the orange square at (3, 3) with distance 5</think>
