Hi:

Do you mean a "Glider"  If you do, go and see the Toffoli & Margolus book
Cellular Automata Machines.  on page 26 is a close up of a "Glider Gun"
There is also a program of life that comes with Quick C which I've used to
view a Glider.  Only one you see.  You must have a high res field or an
empty one to recognise them.  Or you must be able to build an initial state
& know how to construct a "Gun" do get one going.

 Here is what one looks like:

X

    X X
     XX

         X
          XX
         XX

Gliders that is.  Tumbling, or gliding.

I would think a gun design depends upon your particular Viewing machine and
its rules of interaction.  You'll have to know the rules which your system 
operates under to do a glider experiment.  If you are talking about gliders
that is. . .
