The Fourth Pole Was a Door

Su questo pezzo

Three poles, one tower. You know this one.

Then a viewer, @carlosedmunds5531, asked for one more pole and one more tower. Both had to end up in the middle, and the only way through was to become one. From there it refused to stop: more poles, a ring, a whole field, and at the end a map of every arrangement that lifted off the floor into a shape I didn't expect.

I still can't say what the fourth pole is. A shortcut? A third dimension? Tell me what you saw.

If you have a request for the next one, leave it in one sentence below.
