DESCRIPTION:
	CURDLE creates a fractal image of a 'curdle' or Cantor dust.
This kind of fractal is based on a square 'kernel' whose size is
controlled by the KERNEL_SIZE parameter. Every element in the kernel
gets recursively turned into a new copy of the kernel. The number of
levels of recursion are controlled by the RECURSION parameter. Every
element in the kernel which is ACTIVE gets evaluated further. Inactive
kernel elements do not get evaluated. You activate kernel elements by
dialing the CELL_NUMBER to a particular cell within the kernel and
hitting the ACTIVE button. 

	For example, a 3x3 kernel with every other element turned on
looks like this after one level of recursion:
	_____________
        |_0_|_1_|_0_|
        |_1_|_0_|_1_|
        |_0_|_1_|_0_|

	After two levels, you get:
	_____________________________________
	|_0_|_0_|_0_|_0_|_1_|_0_|_0_|_0_|_0_|
	|_0_|_0_|_0_|_1_|_0_|_1_|_0_|_0_|_0_|
	|_0_|_0_|_0_|_0_|_1_|_0_|_0_|_0_|_0_|
	|_0_|_1_|_0_|_0_|_0_|_0_|_0_|_1_|_0_|
	|_1_|_0_|_1_|_0_|_0_|_0_|_1_|_0_|_1_|
	|_0_|_1_|_0_|_0_|_0_|_0_|_0_|_1_|_0_|
	|_0_|_0_|_0_|_0_|_1_|_0_|_0_|_0_|_0_|
	|_0_|_0_|_0_|_1_|_0_|_1_|_0_|_0_|_0_|
	|_0_|_0_|_0_|_0_|_1_|_0_|_0_|_0_|_0_|


IMPORTANT: Large kernels with many levels of recursion can create HUGE
images. If your kernel size is above 4, you generally do not want your
recursion level to be above 3.
