Hello guys,
Today I will show you my very compact piston elevator.

The world download is in the schematic zip file!

Specifications:
-The whole design fits in a 4 blocks wide x 8 blocks deep area.
-The design is infinite stackable in height.
-It's fail safe in singleplayer 1.4.7, 1.5 and 1.5.1 (if you stand in the middle).
-It uses solid blocks on a piston to push you up, rather than just a piston (This fixes the falling-through-pistons bug).
-Once inside, press the button to get to the top.
-If pistons glitch due to lagg, just press the button again and it will reset.

In case you find bugs, you want extra features or you just want to give your opinion: Please leave a comment and I will try to help you :)

Meow,
