; Lava Logo V1.2 (11-2007) script for GIMP 2.4
; Created by Scott Mosteller - 10-2007
; Comments directed to http://www.upstateforums.com (computer graphics and art section)
;
; Tags: logo, lava
;
; Author statement:
;
; Interesting text effects can be achieved by varying font, text-color, shadow-color, gradient and lava roughness
;
; Unchecking the animation option produces a static image with one text layer with shadow (semi-flattened)
; Checking the animation option produces 4 layers, drop shadowed and semi-flattened for use as an animated gif (just save as gif)
;
; Checking raw layers options dispays raw layers only
;
; Compatible with all Gimp Versions 2.x - Enjoy!
