I *think* this is a Coupled Map Lattice
of the Logistic Map. Either way it's pretty. The logistic map is
*x*_{n+1} = *rx _{n}*(

As there are lots of ways to set up the initial values of x, and the various parameters, the contents of each parameter field are passed to eval for evaluation. You can use the variables x and y - these range from 0 to 1, where (0, 0) is the bottom left. Yes, I know, I'm using x for the x-coordinate and also the value of each pixel. Sorry. As well as the standard javascript functions, there is also rnd_gauss() which generates a random number according to a standard Gaussian distribution, and rnd_cauchy() that generates a random number from a Cauchy distribution. Some examples, good for copying and pasting, applicable to various fields, are below. Remember to press Reset after changing the parameters.

`
Math.random()
x+((1-x)*Math.random()*y)

3.0+y
3.65
xx = x - 0.5; yy = y - 0.5; Math.random()*Math.sqrt((xx*xx)+(yy*yy))*1.4
Math.random()*x*x*x
4 - (y*y)
