That is about the coolest thing I've seen in a = while. You win the day. Thank you. I could roll this into all kinds of things.

Henry,

Here's something really basic I just whipped up = that simply moves layers away from a null.  It just pushes = objects away from where the null is when they're closer than the "Distance Threshold" control.  You can increase the amount that = they move with "Move Away Multiplier."

Just paste the position expression from one of = the solids to your own layers and it should work or at least be a starting point to tinker further.  Expression pasted = below as well:

Here's a quick screencapture showing what it = does:
https://www.dropbox.com/s/97yymslvdmjgeez/MoveAwayDemo_01.mp4?d= l=3D0

And here's the .AEP:
https://www.dropbox.com/s/8g3scef520fir3r/MoveAwayExpression_NS= _01.aep?dl=3D0

Not fancy but maybe helpful?

p =3D = transform.position;
nullPos =3D thisComp.layer("Parent And Controls").transform.position;
distanceThreshold =3D thisComp.layer("Parent And Controls").effect("Distance Threshold")("Slider");
moveAwayMult =3D thisComp.layer("Parent And Controls").effect("Move Away Muliplier")("Slider");

distance =3D length(p, nullPos);

if (distance < distanceThreshold) {
    distanceMult =3D (Math.log(distanceThreshold / = distance)) * moveAwayMult;
    delta =3D nullPos - p;
    nDelta =3D (normalize(delta));
    newPos =3D p - nDelta * distanceMult;

those links have since passed on. Character Animator has a physics
