Yes.  MIYAJI Chikara <miyaji at taiiku.tsukuba.ac.jp> wrote something
called QDWindow that does this using MathLink (but this package
presently only runs on Macintoshes because it uses QuickDraw
functionality):

QDWindow, a realtime Graphics Tool for Cellular Automata.

Outline: QDWindow is a sample program in the author's book. It enable to
draw
 two dimensional cellular automata state in realtime.
 For example, life game's evolution can be seen in realtime.

Functions:
        (1)OpenWindow: open window for realtime graphics.
        (2)CloseWindow: close an window.
        (3)SetPort: set a graphics destination to an window.
        (4)GetPort: get a current port.
        (5)MoveTo: move current window's pen to argument position.
        (6)LineTo: draw a line from current position to arguments
position.
        (7)CopyBits: draw a bitmap acording to the value of argument
table.
        (8)CopyPix: draw a pixel on window adording to RasterArray
argument.

The book 

	Network Programming with Mathematica 

which documents a whole suite of MathLink functions by MIYAJI Chikara is
to be published by Cambridge University Press but I do not know when it
will be published.

Cheers,
	Paul
