I started this project by making a function based on the example code in the project description. It was pretty cool modifying the code and seeing what shapes appeared, and I played around with making an overall count variable that caused the size to decrease, increasing the detail. If I had more time, I would have played around with constraining the detailing after the count was above 5000, to constrain it to areas that had not been filled in. Overall, though, I am pretty satisfied with this project.
