Light weight projection... custom laser pointer caps?

Hey there,
Sooo I want to mount a light projector of some sort to a quadcopter. My initial thought is laser pointer, but I would like to display something other than the typical laser pointer fare (middle finger, naked chick...) but to make something else, it costs LOTS of dough it seems, as you have to do some sort of special laser etching to get it right. Anyway, any thoughts on how I might achieve this?
