In this After Effects tutorial, we use a layer’s position to delay its animation based on its distance to the center of the composition. This allows us to use simple animation to make a much larger and more complex effect. To set up the grid of elements, you can position them manually, but I recommend checking out our script, StackIt (http://workbench.tv/products/scripts/....

Expression:
//Apply to Time Remap
pos = transform.position;
delay = -1; //in seconds
x = Math.pow(pos[0]-960,2);
y = Math.pow(pos[1]-540,2);
d = Math.sqrt(x+y);
value + linear(d,0,1102,0,delay);

To change the delay to frames instead of seconds use this:
delay = -10*thisComp.frameDuration;
