Get yourself a Wooly Mandelbrot set!
Can't believe I got features requests for this!! But as requested flat images are available (and are default) - so you can make even bigger plots. Will work on other fractals to plot. Seams some of you want fancy flooring and mosaics :)
Either - look at the center block and use...
/Mandelbrot <width> <length>
...to create a Mandelbrot set centred on the block your looking at.
Or, look at the bottom left corner block of where you want your Mandlebrot set to be crated. then just use...
/Mandelbrot <width> <height> vertical
...to create a vertical Mandelbrot set.
I make no checks on the size of the width and length/height - use values too large and IT WILL crash your Bukkit!
Definition of 'too large' depends on the hardware etc.. But anything over 100 is getting dangerous....
