Quad is perhaps a simple toy for the artistically inclined more than anything else. It begins at the center of the screen, where four ASCII characters wait for you to control them. You use the arrow keys and numeric keypad to send them zipping in four directions (hence, Quadruple) at once, vertical, horizontal, diagonal.
I think it's surprising that a non-graphics drawing method can produce such beautiful
and colorful displays. You might agree if you tried it for yourself.
