Gimp tutorial: Neon Effect

Today's tutorial will be focused in on Gimp.  I found this effect to be quite useful, and I thought I'd pass this information on to the rest of you.  One of my passions is to share what I've learned about artistic design methods with everyone else.  To demonstrate what I've learned, I've provided this tutorial for you to check out.
This tutorial is focused on making a neon tube effect in Gimp 2.6. In this tutorial, we will be producing the desired effect by using the following methods:
  • Color Selection
  • Path from Selection
  • Neon Effect
This tutorial is intended for intermediate gimp users. Please comment on this material and let me know what you think.
