Okay, this may be a 2-rail sin, but with regard to passenger car interiors, has anyone considered the possibility of using transparent holographic window inserts? CAD drawings utilizing known floor plans (http://illinoisharvest.grainge...archtype=all&p=3) could be used. Insert passengers as needed, or maybe even yourself. I know some passenger cars have really great interiors, requiring lots of time or $$$, but this could be an interesting way to do something a little different.
