Well, not exactly no screws but how about no screws that can be seen?  I have viewed a couple YouTube deck builders who were making decks while screwing in from the sides.

Today I found the tool that can do this easily.  It is called the Camo Marksman, from a company called Camo Fasteners.  You place it over your board and it automatically spaces the board and allows you to screw in from the side.

The result is a very clean looking deck, love it.
