I challenged myself into making a 11-piston extender (11 because it's the bigest prime number which is less than 12).
Then i found a way to expand it , so i made a 24-piston extender to prove that it is possible to overcome the 12 blocks puch limit.


It's absolutely useless ... But i love it !



Actually if you have any idea for future useless machine / system / ... , tell me .
