For this project, I started out searching through the wallpaper links provided by the instructions, and i became intrigued by one of the Japanese wave-like prints (which is often used for clothing and paper prints). Inspired by that, I sketched some images down, hoping to create a similar pattern with a bit more dimensionality. For the end result, the most challenging parts were the wave movements created by crossing arc functions, as well as the gradient color choices which took me a while to figure out.
