OPUS: One Page Universal System

In my wanderings on the old internet, I ran across the OPUS role-playing system.  It is supposed to print out with rules on one side of the paper and the character on the other.  It looks pretty smooth and adaptable to me.  For those interested in a quick playing, easy going go then I would suggest taking a look at it.  If you are interested, there is also a yahoo group focused on the game.
