Outstanding! For a minute there I thought you were going to say GIMP. I do not know if it is possible to make something like this with GIMP, but it looks like it might be. If anyone could do it, it would be you! But I love it no matter what program you used! 
Thank you! 
Incendia is actually 3D so it would be very difficult to do this in GIMP.
