Press space to generate the sets. Use turbo mode if you want, doesn't matter too much. Adjust the exponent and colour using the sliders. Press e to write in a specific exponent if you don't like the slider :P Enjoy :)
Credit to @leszpio for some ideas from his scripts. Make sure to check him out! Other than that it was all done by me, although credit is of course due to Benoit B. Mandelbrot :D
