I have a theory about the 3D translites from Stern. Avatar and Tron.
I've noticed that when you look at them with the game off (no backlight) and have a nice light source coming from the front they look really crisp and beautiful and the 3D effect is more pronounced. But when you turn on the game and have it backlit, it looks a bit blurry and some double images and less pronounced with the 3D (in comparison).
My theory is that these 3D translites were designed to be lit from the front.
Thoughts?
