Particles: a field of copies

Particles scatters copies of a layer's shape across its box, for confetti, snow or sparks.

Try this

  1. Press play and look at each artboard.
  2. Select the hearts, open Modifiers, click Particles, and change Count, Size and Spin.
  3. On the third artboard, an Effector after Particles grows and turns the copies it passes.
  4. On the last artboard, the right copies have a copy delay, so their pop ripples.
