What it does?
You pull the lever and the fireplace opens up and closes if you do it when its allready opened, the lever also gets forced off the block.
Go check out MinecraftPG5's - www.youtube.com/watch?v=ySQcKG46DCk

Build Differences!
1. Mine is much more simple and i believe is as fast as you can possibly get it in that small of a space.
2. No blocks that you would be able to see. (No paintings needed to hide a redstone block.)

Uses -
1. Hide your best stuff in this little contraption.
2. Hide your secret base !
3. Your imagination is the limit!

Now i have uploaded my own design of this which is smaller but dosent have a 2 wide area to walk down.
This one was just to see how simple i could make MinecraftPG5s.
