This program renders the mandelbrot set on your Android cell phone. You may tap and drag the screen to produce a selection rectangle that will zoom in on finer detail within the set. Tap and drag again to see even more detail. It's not fast due to the intensive calculations your phone will be carying out. You might want to have your phone on AC power to run this app. The set is the black part. The colors represent the number of iterations to reach convergence around the part that doesn't converge. The Mandelbrot set. Thanks for trying this program. Please click on and visit our supporting advertisers. Thanks....
