Crewdroog: I am sorry. I thought this explained it in a simple way. :( I'll just stop then.
tinyE: You did a fine job explaining it. We just can't figure out why. :P I could see hacking one of those gigantic scoreboards or maybe the Goodyear blimp to play Quake on, but a "device used to measure the frequency of an electrical signal over time..." It boggles the mind.
that is the idea ?
doom and quake tend to pop up on the strangest of places
mostly done because its possible or to make it possible then because its practicle
