I have been searching the Internet searching for the solution, but I have yet to see it...
Just to clarify I am NOT looking for...
I want to solution to the following gate...
The Gate is very limited to the space above the opening as I can not place any redstone wiring above the Gate's Opening. I'd prefer the solution opens the gate Side to Side. I already know how to open it Up & Down. I was thinking the solution would include the use of Sand and or Gravel. as you could force it upward and let it fall when the pistons are contracted.
