Nathan!

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

Henry,

Here's something really basic I just whipped up that simpl= y moves layers away from a null.=C2=A0 It just pushes objects=C2=A0= away from where the null is when they're closer than the "Dis= tance Threshold" control.=C2=A0 You can increase the amount that t= hey 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.=C2=A0 Expression pasted below a= s well:

Here's a quick screencapture showing what it does:

And here's the .AEP:

Not fancy but maybe helpful?
=C2=A0- Nathan

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

distance =3D length(p, nullPos);

if (distance < distanceThreshold) {
=C2=A0 =C2=A0 distanceMult =3D (Math.log(distanceThreshold / di= stance)) * moveAwayMult;
=C2=A0 =C2=A0 delta =3D nullPos - p;
=C2=A0 =C2=A0 nDelta =3D (normalize(delta));
=C2=A0 =C2=A0 newPos =3D p - nDelta * distanceMult;
} else {
=C2=A0 =C2=A0 p
}

About a decade ago, ways of doing this abounded on the interwebz...
those links have since passed on. Character Animator has a physics
engine I may explore.
