I was experimenting with the BetterThanWolves mod one day, and I decided to try and make a 4-floor elevator that worked like a real one. This is what came out. You can push the button at any floor to call the elevator to that floor, and you can push the buttons inside the elevator to go to the other floors. The only part that isn't like a real elevator is the fact that it doesn't have a floor request queue, so if it is moving to floor 1 and somebody calls it to floor 4 it will turn around and go to floor 4. This project requires BetterThanWolves (duh...) and the Wireless Redstone mod (yay no wires!).

P.S. It even includes an automated hemp farm!
