I am attempting to build a facsimilie enigma machine, I would like to know how best to create an effect so that when a key is pressed a corresponding letter appears to light up. I am not so much a graphics newbie as much as a graphics incompetent, so if someone could give instructions for dummies. btw I am not looking for an animated image, I can take care of the transitions between on and off, I just need to create the two image states. Hope this makes sense.
