In this project, I iterated some simple for-loops for each curve. In some cases, dynamic to the mouse’s X position, and in other cases, static. I think what’s nice about the movement is that it’s a dynamic set of strings, tied to a static set, which creates a satisfying connection between their visual elements and rhythm!

This time I didn’t dabble as much in composition before writing the program, instead, I really enjoyed seeing the composition emerge as I played with the numbers. Another nice touch which makes the interactions a bit more satisfying is the additional randomized color sets.
