I have been digging into this lately and some of the stuff really impresses me. The Matrix pachinko and a few others have a few layered LCD screens to give depth for 3 dimensions. I am really impressed with the animation on these games as well. I liked Wizard of Oz but the animations feel flat and lacking energy in comparison to some of these pachinkos. The Matrix has layered LCD like i mentioned earlier and led light and moving parts like a cell phone that pops out when called. I don't think it would hurt to just dump the traditional pinball even if they don't look as nice when off. Imho, this where pinball backglasses should be or would have been had the industry been as funded as the pachinko industry is in Japan. If I was running a pinball company, I think I would farm out my backbox animations and art to a pachinko company or hire on some guys with pachinko experience. It is like you have two very similar industries that diverged 15 years ago and for whatever reason the one that lagged behind never thought to learn or copy what its cousin had been doing for awhile already. These machines are all years old and they do their displays, animation, and lighting better than pinball. We get excited over color changing LEDs in WOZ and ST but that shits been done for awhile already in Japan.
Here are some of my favorites:
Matrix (watch the cell phone and machine gun that pops out during fever mode)
Tom and Jerry
Star Wars
Ultraman
Yamato 2
Back to the Future
Cute Honey
Woody Wood Pecker
Jurassic Park (watch for the dinosaur eye that moves around the hole to look at you)
Macross (cool as hell)
Superman
Tom and Jerry (one hell of a beautiful machine)
Wizard of Oz for comparison
