Double Helix staircase


After a recent visit to Chambord, I decided to have a closer look at the double helix staircase.
This is a simplified version I made recently.

If you look through a window on this staircase at someone else, you cannot catch up with them unless you exit one staircase and come round to the other side.


i wish i could response in one character, because then i would just say :heart_eyes:


Nice work!
