i don't have a way to record so i can show how to do but its just a shredder, nothing to complicated
to add (on pc atleast) go to start and search %appdata% and navigate to the minecraft folder (default C:\Users\~name~\AppData\Roaming\.minecraft\saves) and put the file in the save file and open minecraft.
objective find the right combination of switches to provide power to red wool, then use the 10 pistons to make your way from wool to wool to get to the room at the end containing the tower of pimps Note: the switches are set up so turning some switches on will kill power to some red wool, and some switches will give power to more than 1 wool)
rules If you fall or miss a jump you must destroy all of the pistons you placed, gather then up and start over.
If you put the code in wrong and get to a wool platform that does not provide power to your piston, gather all your pistons and start over
you can only place pistons on red wool, and only facing straight up
the 1st person to enter the room containing the tower of pimps is the winner
