; Genrates what looks a little like the back of an old circuit board.
|
|
; Looks even better when gradmapped with a suitable gradient.
|
|
;
|
|
; This script doesnt handle or color combos well. ie, black/black
|
|
; doesnt work..
|
|
; The effect seems to work best on odd shaped selections because of some
|
|
; limitations in the maze codes selection handling ablity
