Are you serious? Because that is extremely basic redstone. I'm talking about complex redstone builds on Massivecraft. They don't have to be practical, but I don't want any pictures of 2x2 piston doors. Try making a 3x3 door, or maybe even bigger if it is possible to make a ghost block engine on Massivecraft. I once saw a video of a 7x14 door using ghost blocks created by a generator with rapidly-pulsing pistons below the door.
