When someone finally realizes that an inverted webcam could be integrated into the back-box and that pinball fans could network together using wifi, the LCD is going to become a whole lot bigger deal. When I can play a game with friends across the globe, watching their game on my LCD, chatting via integrated voice chat and maybe, just MAYBE even influencing the game (think remote player controlled playfield toys, or - perhaps - modes only available or even accessible in "remote player mode" ) then the LCD is going to have a market that no DMD game can ever have. Weekly WoZ tournament from the comfort of your living room/game room, anyone?
If I wasn't poor I'd already have a patent.
