I love the backglass/screen on WOZ. That being said it's applications seem pretty limitless. You could make a generic enough playfield lets say music based and then download customizable skins for the backglass for your favourite bands that could scroll through pics and even show videos.

Would be great to even have a camera or two in the head so you could see all the action at tourneys.

p.s. banana flippers
