This tutorial can be helpful if you want to create a really fast Rim Light in 2D. 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 bring a Matrix Node from here: Filter → Matrix... and select the dimension of the matrix. In this case 3x3.
When you will find this Textfield, you can copy-paste the values directly in another Matrix 3x3 node in Nuke.
