Gimp Tutorials.net (one of my favourite Gimp tutorial sites) has developed a great tutorial showing how you can create this fantastic effect:
It uses a number of techniques including glows, easing and path tools and can really improve your skills in The Gimp. I wouldn’t recommend this to beginners in the Gimp but for more intermediate users, this is a great tutorial to have a go at.
