Yeah that technique works well with flat lenses, I learnt it back in high school in shop class. Our teacher was a car guy and one project was working with plexiglass, because he was making custom lenses for a Trans Am.

He didnt use the diamond cut diffuser though. He routed out "Trans" in one lense and "Am" in the other (he jst used clear plexiglass for the routing), but explained that we could use the light diffuser from fleurescent lights to to duplicate a tail lense.

I guess you could get creative with a router and a clear piece and make your own patterns. Do <<<<<< & >>>>>> routing into the clear, or any combo you wanted.
