About changing the gobo on your laser, Lasers do not use gobos, they aren't like moving head spots where they shoot light through a gobo wheel, lasers create the image using really fast moving mirrors. And the ADJ royal sky is not capable of doing custom shapes or patterns. you may email me and i can give a recommendation for lasers in email. jamesk @ elation lighting dot com
