Space Invaders. The chaser lights that strobe to the sound (doo, doo, doo doo..) and get faster and faster. Still to this day is my favorite backglass / light show. Mirror backglass with the most menacing artwork. Love everything about the machine !

Having played Dungeons and Dragons with the topper, there is a mode where the topper window with a dragon is lit and you are blinded by lights from the sides of the topper. Scares the crap out of the players - and looks cool !

Fire ! Champagne edition with the rolling flames. Amazing effect !
