When Space Invaders was first released in Japan in 1978, it caused a shortage of coins that was only abated when the yen supply was quadrupled. Dang, that's a popular video game. Now, you can have an arcade-style version that's a little easier to move around than a 350 lb stand-up arcade console. Featuring an arcade-style joystick, authentic arcade sounds and graphics as well as a boss key (mute button) and a pause button, the Space Invaders Desktop Arcade is the best addition to your desk since you taped up that really funny Dilbert on your computer monitor.
