Building Images
How do I make an building images?
Working on doing the opposite of what Szenia did and also in a given direction.Forked from Szenia Zadvornykh's Pen Shattering Images.. What is a building images? How do you make a building images? This script and codes were developed by Zach Saucier on 20 August 2022, Saturday.
