The screen name is obviously that of M.C. Escher. However, the IV comes from his woodcut of Circle Limit IV, also known as Heaven and Hell. M.C. Escher is, in my opinion, the greatest artist to ever live... Anyway, that's where the name came from..
My name is Dave Kiger, and I'm living in York, PA.
I am also known as maniac, ungod, kiger, and a few other things.
