I designed this one probably four months ago. Due to the complexity of it I was hesitating to try my hand at digitizing it, I just couldn’t figure out if it would be possible to make in perspective or how to start! Finally I decided would just try and see, and it eventually worked itself out :)
From the left the construction starts out with only two steps, but as you move along the object the number exponentially increases. This while no step surface is ever subdivided.
