Parkour Idea

This is one of my ideas for a parkour map or adventure map. Once you jump from the diamond ore to the other one the pressure plate activates and pulls the block into the wall and then the 3 surronding pistons activate stoping the flow of lava. Of course there is no lava in it so that you can get an idea of how it is wired. The only use of the 3 surronding pistons is to stop the flow of lava from going downward and destroying the lava.

You can use this wherever you want and it doesnt matter if I get credit so please dont ask. Thank You.
