This tutorial can be helpful if you want to create a really fast Rim Light in 2D. You just need the matte of the character/object you want and move the rotate slider.
First of all I would like to thank Sabine Janetzka for introducing me to this technique with the Matrices.
You can download the Gizmo for Nuke here:

Overview
In Nuke, create a Matrix node from here: Filter → Matrix... and select the dimension of the matrix. In this case 3x3.
Wherever you find this text field, you can copy and paste the values directly into another Matrix 3x3 node in Nuke.

This is our original image: a simple 2D circle. You can get it with the Radial Node in Nuke.
