How to create advanced glitter using expressions & Particular

In this tutorial, Creative Cow leader, Michael Park, demonstrates another, more advanced method for creating shimmering glitter particles using Trapcode's Particular in After Effects. The main advancement is the implementation of 3d rotation of the glitter particles, as well as using expressions to convert the rotation of the particles in all 3 axis to drive a greyscale map, which in turn is used to color the particle using colorama and create the shimmer effect when the particles face the camera.
