Mirror blades with a red tinge on them would be a good addition.
Even stickers as big as and shaped like mirror blades with excellent matching zombie artwork on them would be a cool addition.
Someone with talents on Photoshop or some other art program might be able to sell some sets as a mod and might make some $$ doing these.
Any thoughts, anyone thinking of designing these side wall artwork ???

head to Facebook and look up Pinball Mods - side graphics already in first draft and the same guy did a tron set of mirror blades with graphics.
