This is a tiny 3 high expandable wall door. It comes in at 3x7x12 or 252 blocks in volume. The mechanism is fairly derpy and I didn't expect it to work. It's also not VERY reliable, but it's not bad in singleplayer when you're not recording. Some people might say that this isn't very compact because the input isn't on the wall, however it is widely recognised in the redstone community that the input doesn't count, no matter how awful.

This is what I deem to be the worlds best 4x4 piston door, because its fast, reliable, compact and works in Bukkit 1.5.2. Its also really easy to remember how to build and even a tree could do it :D Thanks to g4me4u for helping with this!
