This is a communication device used originally to train monkeys with a type of language.
I got the piston Idea from my brother SirGary......
Don't complain about compactness cause there is a new one coming out some time later 2014.....
TP TO SPAWN IS BROKEN

Heres my second version of my Communication device used to teach Monkeys a language using buttons, obviously the redstone current stops after about 1 second with buttons so I used levers.

Anyway this is more compact then my last one, but a better one will be out later.
