Hehe! Thanks alot!;D sorry I am answering your question only now...
Yes, I tried to make a better version of the noble collection map! so I put the staircases, I believe I made almost the same procedure they did on the original map from movies.
This technique it is called "Kirigami", "Architectural origami", or even "pop-up-cards", you just have to cut the paper in certain areas and fold it!
I am from Brazil, so I don't know how I could sell to you, but is an great idea! Do you have any suggestions how I can sell it to you?
Thanks again!
