Mandelbrot asked the famous question How long is the coast of Britain? Modify Brownian to get a program BrownianIsland that plots Brownian islands, whose coastlines resemble that of Great Britain. The modifications are simple: first, change curve() to add a random Gaussian to the x-coordinate as well as to the y-coordinate; second, change main() to draw a curve from the point at the center of the canvas back to itself. Experiment with various values of the parameters to get your program to produce islands with a realistic look.
