Speaking of scary changes. The idea that it's moving at all is pretty frightening. ?
I went up the Leaning Tower of Pisa as a child...towards the top, there is a grate on the floor that allows you to look straight down through the center of the tower...I froze and could not cross it. My dad yelled at me and could not get me to budge...I remember him spanking me across it...made me afraid of heights until I overcame it through aversion therapy...
I crossed it again later in life with no problem...and yes, the lean is cool...but really not noticeable when inside...
