In this tutorial we create and animate some shapes in After Effects using Shape layers and the iExpressions Repeater expression. In contrast to the repeater feature that is built in to After Effects, this repeater does not distribute lots of copies of a shape in space, but instead concatenates all shapes into a single one. We apply to rounds or repetition one after the other to create and animate even more complex shapes out of very basic ingredients.
