Cool jungle text effect in GIMP (or mother of pearl in silver text effect)

GIMP tutorial on how to make a text effect. Step by step clear explantion.
In this GIMP text effect tutorial I’m working with script-fu layer effects and with selection. You will learn how you can use selection to create borders on text and other cool effects.
You’ll also know how to the Gradient Difference techniques in GIMP to get really cool effects.

Not sure what to call this GIMP text effect though. The text itself looks like mother of pearl in silver.
