For this project i wanted to create something that resembles a stage lighting design, hence the creation of this neon color drawing. I thought the corner drawings were actually not as hard as aligning perfectly the middle section (the two horizontal lined triangles).

When I saw the project, I was reminded of the 2013 Great Gatsby movie poster, and I wanted to make a version of it using the string art. I thought this project was going to be a huge difficulty for me, but after really looking at it and asking tutors, I got a better grasp of the assignment and was able to make better guesses at figuring coordinates out. I tried to use the x1,y1/x2, y2 concept listed in the instructions as well as the x1 += x1StepSize, because I figured it was probably the simplest way to help generate the “curves,” so I could focus more on creating a better design.

A really rough sketch of my initial idea. It ended up changing, because I felt like it originally looked too busy. I did have help from the CS pedagogy tutors in trying to figure out how to approach this assignment.
