loopOut("cycle")

Original Code (composition 2000 x 2000):

radius=500
angle=time*100
x=radius*Math.cos(degreesToRadians(angle))
y=radius*Math.sin(degreesToRadians(angle))
centre=[1000,1000];
add(centre,[x,y])

Carousel 1:

//position
radius=thisComp.layer("CONTROLS").effect("Circle")("Radius")
angle=(360/((thisComp.layer("BOTTOM_LAYER").index)))*index;
x=radius*Math.cos(degreesToRadians(angle))
y=radius*Math.sin(degreesToRadians(angle))
centre=thisComp.layer("CONTROLS").effect("Circle")("Center")
add(centre,[x,y])

//rotation
-parent.transform.rotation //(parent objects to CONTROLS layer)

Carousel 2:

//anchor point
a0=width/2;
a=(thisComp.layer("CONTROLS").effect("Circle")("Radius"))+(height/2);
[a0,a]

//rotation
(360/((thisComp.layer("BOTTOM_LAYER").index)))*index;

//parent objects to
