	Create a small solid layer (say 15x15). Make it 3D.

	Add this expression to the point control.
	Adjust minSpeed, maxSpeed, maxDrift, and the two rotation parameters (m) to suit your needs.
	If you decrease minSpeed, you may have to increase the "life" parameter of the point control or the particles may disappear as they reach the bottom of the page.
	Duplicate this layer until you have enough particles (50 to 100 maybe?). */

Constant Rotation Per Second. No key frames needed to make a simple 360 rotation.

ryanbru0803 / squash-and-stretch.js

Last active February 26, 2020 08:46

The squash and stretch expression should make your animation a bit more alive by adding a proportional squash and stretch scale to your shapes or images.

	maxDev = 13; // max deviation in pixels
	spd = 30; //speed of oscillation
	decay = 1.0; //how fast it slows down

Last active January 22, 2017 16:10

In After Effects, add this code to the position property to ease an object right, left, up, or down.

	//Right
	x = position[0];
	y = position[1];
	d = 262; //Distance in pixels
	ease(time, 3, 4, [x , y], [x+d , y]);

	//Left
	x = position[0];
	y = position[1];
	d = 262;
