This week for my project, I decided to make several repeating turtles with a changing background. It kind of reminds me of the pattern we had to create for a project in a past week. It was fun revisiting the use of turtles, and I enjoyed making turtles that looked totally different from the meanders we created for the assignment last week. I think the changing background adds a cool visual effect, and it was something I came up with during the course of making this project. I did not really start this project with an exact plan, like I usually do, but I enjoyed it nonetheless and feel much more comfortable using turtles now.
