Bringing the last elements together... We are definitely on the final 'last stretch' now!
And there it is: a moving (but still amputated) tower! We attached the 4 muscles in between the two units to try out the movement. Slowly and gracefully it started shifting from one side to the other. Even more remarkable, the structure straightens itself when equal pressure is being put in the four muscles at the same time. So far so good!
