Fancy Elevator in Minecraft - 1.8

Today I made a command block elevator in Miecraft. I know that there are a lost of elevators made with command blocks, but this one is more fancy, having sounds and delays to make it like you really have to wait while going up the elevator!

If you push the up or down button, a chain of command blocks and repeaters will go off. First, a fill command will take away redstone torches under the elevator(iron) doors. Then, there will be a dely of about 3 seconds, and you will be teleported directly upwards from wherever you're standing in the elevator to and identical copy of the elevator above. After that, you will here a sound which means you are at the next floor and a fill command will place the redstone torches at the elevator you came from.

To use the world, take the folder out of the .zip folder and put it in the saves folder in your .minecraft folder.

**Note: A custom texture pack is needed for the elevator doors - www.mediafire.com/download/2uli9dzjp01v25x/Elevator+in+Minecraft+Texture+Pack.zip
