What I posted should give you the location of the parented null’s anchor point in world space. I guess I don’t completely understand what you’re after. Maybe you could post a screen shot of how you have things set up.

[Dan Ebberts]

No, you can put them anywhere, you just have to link to them with the c1, c2, etc. variables.

Try it this way:

L = thisComp.layer("Null 1");
L.toWorld(L.anchorPoint)

You could use color controls (or fill effects) and modify the first part of the expression to define the color array (with as many colors as you want) this way:

c1 = effect("Color Control")("Color");
c2 = effect("Color Control 2")("Color");
c3 = effect("Color Control 3")("Color");
c4 = effect("Color Control 4")("Color");
c5 = effect("Color Control 5")("Color");
colors = [c1,c2,c3,c4,c5];

Try it this way:

compLength = thisComp.duration;
if (time <= 1.2)
  linear(time, inPoint, 1.2, -1035.6667, -2655.907)
else  
  linear(time, compLength - 1, compLength + .2, -2655.907, -7500);

Just a lazy way to initialize two variables to the same value.

[Dan Ebberts]

Yeah, OK. Maybe something like this then:

maxSpeed = 10;
minSpeed = 0;
maxDistance = 500;
target = thisComp.layer("Target").position;
pointer = thisComp.layer("Pointer").position;
accum = d = [0,0];
f = timeToFrames(time);
for (i = 0; i <= f; i++){
  t = framesToTime(i);
  d = target.valueAtTime(t) - pointer.valueAtTime(t);
  factor = linear(length(d),0,maxDistance,maxSpeed,minSpeed);
  accum += normalize(d)*factor;
}
value - accum;

[Dan Ebberts]

Maybe something like this applied to the Offset Turbulence parameter of Fractal Noise (or the position property of a large texture layer):

refPoint = [thisComp.width/2,thisComp.height/2];
distanceFactor = 2;
delta = thisComp.layer("Target").position - refPoint;
value - delta*distanceFactor

[Dan Ebberts]

Probably something like this:

s1 = effect("Slider 1")("Slider");
s2 = effect("Slider 2")("Slider");
s3 = effect("Slider 3")("Slider");
s4 = effect("Slider 4")("Slider");
"CUBIC-BEZIER(" + s1 + ", " + s2 + ", " + s3 + ", " + s4 + ")";

This should help explain the problem and provide potential solutions:
