The Web log Tokyopia reports on a Tokyo skyscraper that has a massive game of Space Invaders porjected onto the side as part of the game's 25th anniversary celebration.
It turns out they are running Space Invaders battles on the stage in front of the 109 building and they are displaying it live on 2 of the large TVs in front of the station including the live play by play annoucing from a cute Japanese hostess.
It's a special version of Space Invaders where the screen is split similar to most puzzle games (ala Tetris) except in each half of the screen is Space Invaders. Actually it's only a quarter of the screen because the top half of each column is an upside down mirror of the bottom half of the other player's column. The goal is to shoot through your invaders and then shoot the other guy.
It's all pretty cool and between games there's this way hip techno 3d flash like Space Invaders mix thing going on.
