Speaking as someone who had actually art directed a pinball LCD my take is this: if you don't have a huge budget and talent on deck to try and do the JJP slot machine look then just don't try it. JP does amazing work for JJP, but it's just one approach, there's really no need to copy it. I frankly find those LCD screens too busy most of the time, it could be dialed back some easily.
Alien was a challenge since the company fell apart, we had no access to the game, etc, but I still think we delivered a pretty kick ass 1.0 animation package for it. On a shoestring budget, I can tell you that. If the game was still in production and we were being paid to keep updating it there's plenty I'd love to change and upgrade, but so it goes. We did it by coming up with some internal rules for how things would look, how we could disguise our limited assets, and how we could do justice to feeling immersed in the world of the game.
Alien aside, Alice Cooper has IMO the best indie LCD package so far IMO, really works well. It doesn't bite off more than it can chew, it stays true to the look of the game and theme, and uses creativity in place of doing too much. And that's IMO the magic secret, be creative and think about what you really need to show and how you can do it well, rather than falling down a '90s CD-ROM trap.
I don't really feel like giving away free ideas to anyone, but I've sketched up plenty of creative LCD uses that haven't been done before, and I'm sure I've only scratched the surface of what can be done. Just means caring and being creative. The message I'm hearing right now is "we don't really care", and you get what you get with that approach.
