Stonehenge Is Going Nowhere

Like Stonehenge 1, this is an exercise in having a feel for mechanics.

One way to think about this one is that when you push the stone from left to right, the top layer of logs wants to move clockwise, and from left to right. The bottom layer of logs then wants to move anti-clockwise, and from right to left. However the bottom layer cannot move left since the logs on the top layer are going right.
