Mmmmm...I think it needs a sense of length & direction & I don't think either graphic does that.

Maybe something like:

	         . .          . .          . .        
	       .    .       .    .       .    .       
   -----------.      .     .      .     .      .     .-----------
	              .   .        .   .        .   . 
	               . .          . .          . .  

Not enough direction--how 'bout:

	     ()-------------------------)      	       	
	   (    )             		  )       	
----------(--o   )			   )------------
	   (    )      	       	       	  ) 
	     ()-------------------------)   

I'm not terribly fond of that one either, hmmm.
