Video: A pipe organ can cost more than $250,000 and weigh hundreds of kilograms. Not this instrument. The paper organ built by master craftsman Aliaksei Zholner costs and weights only a fraction of that -- and it works just like the real thing.
According to his blog post in a paper-builders forum, Zholner built the entire system from paper and started with only a couple of small paper reeds and pips. He then built the housing to hold the organ pipes together and put together the keys and triggers to activate the pipes. If only you could build everything out of paper.
