A giant computer controlled array of pixels, each consisting of a small gas flame which can be turned on and off quickly. The player controls a sliding platform at the bottom of the display of moving rows of invading aliens which fires real rockets at the array. When they hit, they really explode (again controlled by computer) and the gas flames are turned up to maximum, causing an explosion-like effect. The same happens when the player's platform is hit.-- nineteenthly, Mar 13 2008 Excellent - I'd like one please. The Virginia creeper on the south side of the west wing is dying, and we'll need something to replace it.-- MaxwellBuchanan, Mar 13 2008 random, halfbakery
