Originally I had planned to make two branching clusters of branching lines to simulate puppeteer strings, but felt that it lacked variety.

In the end, I opted to create a violin (which I played from elementary to high school) using the same technique I had in mind, but varying the spacing and positions of the “curves” to: a) draw the individual strings and overall bow and b) create a slanted perspective using an artificial “zoom” effect.
