I have created some parametric x,y functions that you might call iterative, in the form:
loop
x=x+f1;
y=y+f2;
where f1 and f2 are simple functions, sometimes including a condition.
The results were surprisingly diverse, generating tendrils, procedural maps, orbits or "serial" graphs. The most interesting are the tendrils. The expression is:
loop
p=.9*p*(1+.1*sin(.2*time*sample.1*time))+ 2*cos(sample.1*time);
x=x+sin(p);
y=y+cos(p);
It evolves with time, creating new leafs.
